My init.el adds quite a bit of functionality but doesn’t change many default settings at all.
In some ways working through setting up your .emacs the way you want it is a great way to learn the tool.
Vanilla Emacs keybindings, or cua-mode, are fine, and probably less of a learning curve than going modal. If you're already in that headspace, all power to you, but half the reason I got into emacs in the first place was because I couldn't stand vi.

Try using that config 25% of your work/productive time for 1 month.
Then if you are annoyed by how much time it takes try using doomemacs for the same 25% time.
At the end of this you'll know if/which emacs approach is for you.
25% isn't a hard number btw, tailor for the process to be frictionless and useful for you.
1. go through the entire built-in tutorial (which it will prompt you about on first load)
2. just adopt doomemacs or spacemacs, which are very large complicated default configs that are easier for vim users to start with
