Can you just not use those feature which you do not need?
I say this because iterm2 with zsh and oh-my-zsh is what I have used for years and I barely scratch the surface of the tools or any of the features, but it's just a comfy environment that works fine.
XQuartz with xterm is one possibility. XQuartz helps with bringing up a GUI from a Docker container. Sure, `xhost +localhost`, but minimalism is only a .pkg install away.

I think the plain xterm does not have many shortcuts built in, but could be wrong.
With a slow motion camera I can prove that alacritty is faster / more responsive, and I think I can feel it, but it also has slightly more bugs and uses massively more battery. One funny issue is that I can’t screen share alacritty in zoom.
I use tmux/neovim so I’m in the terminal 100% of the time I’m working.
There are better options.
