Dependency problems are mainly resolved with uv - try it.
1 way to do things - not sure what you mean. It's a general purpose language, if you dont like something there's probably a different library that may do it the way you like (eg, don't like exceptions, use a library that mimics rust style Result values; don't like oop, don't do oop, functional programming is certainly possible in python), or easy enough to start creating your own private utility libraries that do things your way.
Xonsh was okay. Idk if I'd use it again. I'd probably just use python to invoke external cli programs using subprocess. I used xonsh for scripting before. I recall it having a slightly slow start up - I launch shell frequently so that's a no-go for me to use as my default shell.

And I looked at alternative scripting languages. Racket, D (has a single file script mode), ocaml, etc. Honestly python seemed good enough, even with its warts, especially with uv to manage deps without a whole formal project needing to be setup for a script. Stwp up from bash. Most of my use cases are fine with argparse + subprocesses + a unix shebang at the top + "chmod +x", with uv handy if I need a external library.
