Alternatives to Oracle APEX

The only two programming languages I know are Python and Dart, I fall in love with Dart when I learned about the type safeness, ease of refactoring, and the help of the IDE. I have an idea for an app, a simple app, but I need SEO and server rendering, and I also want it to be available on all platforms. I can't use Flutter or Dart anymore because of that. I have been searching and looks like there is no way to avoid learning HTML and CSS for this. I want to use Supabase as BASS, at the moment I think that I have two options if I want to learn the least amount of things because of my lack of time available:

1. Quasar Framework: They claim that I can do all the things I need, but I have to use JavaScript, and I am going to have all those bugs with a type-safe programming language avoidable. I guess I can use TypeScript?, but that means learning both, and I am not sure if I will be able to use 100% Typescript. Besides Vue.js, Node.js, etc.

2. Blazor and .NET: There is MAUI with razor bindings in .Net now, and also a Blazor server. And as far as I can see, the transition from Dart to C# will be easy. I guess that I have to learn some Javascript here and there, but I have to less things I guess, am I wrong? But Blazor is a new technology, Vue is widely used.

My company wants to make some relatively small, self-contained web apps to go through specific engineering analysis workflows.

Each app would involve:

(a) User inputs numbers and tabular data either in a table or from a csv import

(b) App makes plots of this data

(c) App performs calculations based on user input and outputs results as either plots or numbers or tabular data

It seems like there must be zillions of applications where people want these things, so I want a 'low code' approach that already handles a bunch of details so we don't have to. Experience in the past with Angular has involved, in my experience, a lot of low-level coding to 'reinvent the wheel', creating capabilities (like menus to control plotting options like font size) that I'd expect to be very common.

Specific wants:

(a) Plotting capabilities with prebuilt convenient plotting controls

(b) Ability to 'save' and 'load' (as in, you do the analysis and get results and want to save so that you can reopen this save environment with the data and analysis, as if you'd never closed it)

(c) For specific components, ability to swap out the built-in components with a customized plot/widget.

For example, with (c), we might have a situation where we do want to make a custom plot or tool, and would like to be able to drop that into the general application

Question is - does something exist that does what I am describing? What would you recommend? On our list to check out: Microsoft PowerApps , Dash , UI Bakery, Retool , Tibco Spotfire , Outsystems, Zoho, Creatio, or any other suggestions.

Other considerations:

(a) How easy are these apps to maintain (i.e., do they frequently make non back compatible, breaking updates, like they do with Angular)

(b) Need excellent security so I can deploy web apps for large companies

(c) General ease of use (would like to be efficient with developer time).

I'm standing up a web app that needs functionality, including profiles, directory, scheduling, video meeting, and payments.

I considered Wix, but I'm not sure it will meet these needs. I'm interested in no code / low code tools in order to move quickly but struggling to navigate through all the options. Any advice on how to select no code / low code tools like Webflow, Bubble, stackbit, Retool, BaseDash, Glide , airkit, adalo, stacker, unqork, tiled, airtable, zapier, v.one, candu, bravo studio, amazon honeycode, unstack, dittofi, makerpad, softr, appsheet, etc.?
