Use whatever you know best. I'd use firebase and google cloud stuff because I know how to get something working with them quickly. My personal stack would be: Firebase for storage, cloud functions with python if logic was simple and mostly client side, Flask in a VM if I thought it would need more complicated stuff (like image processing) on the server side. Bootstrap and Angular for the front end. But there's no strong reason for those other then these are proven, I know them already, there are plenty of equivalent options. Recently I've been playing with Blazor+WASM and that's looking really promising and allows sharing C# code between client and server (and potentially a native desktop app as well), and to me is more ergonomic to program in, but I haven't used it for anything non-trivial yet.
