Next.js

My advice: Next.js, PostgreSQL (supabase). Next.js can handle API routes natively, which eliminates the need for Express.js. You can define your own backend logic, such as handling database interactions (CRUD operations) through these routes. For UI/UX you could make use of Nyxbui + Aceternity (based on shadcn, framer-motion, and some other amazing frameworks/libs/modules). But only combine nyxbui & aceternity if you feel confident with very advanced frontend logic, otherwise just use the basic Shadcn. Do not forget to make good/secure RLS policies and take care how you are handling the caching for your routes when using next.js.

I would use Framework7 React for my frontend and Supabase to store the data. Framework7 is mobile friendly, easy to use, and has tons of prebuilt features and components. Supabase is also easy to setup, has a free tier which allows a decent amount of data storage. And above all; it's API is super easy.

Before you look into Next.js, you could probably leverage feather.js here. Because the Website you linked is very basic you could be able to rebuild this page in mere moments.

You should get away as fast as you can from WordPress (not that it does not fit the task... but every WordPress Site is a thousandfold slower than even an averagely complex node.js implementation - just don't do it if you call yourself a developer :)

Use WordPress if you want it for something small or medium-sized. Don't waste your time building it when you can do it on WordPress easily.

Why would you allow your decision to be driven by the limitations of a hosting account? MySQL is a relational database, and typically you need a solid understanding of relational database design and SQL. MongoDB as a so called "Document database" is not relational. You can associate several MongoDB collections together if you understand the basic concepts behind, it, but in general, MongoDB does not have nor require a fixed schema. It can do many of the things a relational database can do, particularly if your data fits nicely into a hierarchical structure. It also often appeals to people like yourself that are working with a javascript stack, as the interface to MongoDB is json. If you can install a package onto your host, then you should be able to use MongoDB. With that said, you can do all your development locally using Docker containers. I would not suggest that you let important design decisions be dictated by what one shared host allows you to do.

I think you should use MySQL but with php or Python because e-commerce websites needs to be fast and reliable with more admin tools and you’ll find what you need and more in e-commerce when using php or python frameworks with MySQL database.

Example: Using django (python framework) with MySQL gives you administration dashboard that you can use to edit in a lot of things and django also supports a lot of things like generating ready forms linked to the models you generated

hello, check out astro.docs and firebase hosting https://firebase.google.com/pricing. I really like their island inftastructure and its easy to deploy too. about the hosting you have a very cheap plan now with firebase you will pay as much as you use. You can also use your current hosting provider and move to firebase or somthing else if you run into the limits of your current hosting.

Consider leveraging Next.js for your NGO's knowledge-sharing platform, ensuring a seamless user experience. Combine it with Payload CMS for flexibility, moving away from WordPress. Optimize costs by exploring serverless architecture on platforms like Vercel or Netlify, allowing scalability without a substantial increase in hosting expenses.

Without a doubt, you will want PostgreSQL as a database. I imagine that the analytics will become important with time so that you can track activity around the video consumption.

Django is a batteries included and it will help you get to MVP quickly. Once you have settled on the functionality that you need for the chat and video application, you can then build a leaner, custom app with FastAPI. Next.js is a good frontend framework. Depending on how good you are in front-end engineering, you can also look at SvelteKit which works better in using HTML5 web standards and is less bulky that Next.js. Both are supported by Vercel, so they will be around for some time as technologies.

I think this is a good choice, so many design elements are considered for you such that even if you're not a great designer, as long as you're focused on layout and functionality it's relatively trival to go in later and apply themes and custom widgets. I'm using flutter for the same reasons as you it sounds like and for what it's worth people have been extremely pleased with the tools I've built for them even though I didn't really consider design. Knowing I don't have to worry about making things pretty for them to be attractive to end users is a huge boon for me and I hope it can be for you as well.

RE Flutter Web, I'm sure it will improve with time, I've only ever really seen it slow when it's first starting up. but once the app is "loaded" into the web server so to speak, it's generally been pretty performant assuming I'm doing things like caching appropriately.

I got a task at my previous company to compare between Flutter and RN and Xamarin. And Flutter was the better choice among the others, that was before version 3, and now after version 3 it becomes better, so I would recommend Flutter for you.
