Is there a GUI for remapping the keyboard in Ubuntu 20.04 LTS? For example, I want to swap ctrl, win and alt keys to win, alt and ctrl respectively. I've managed that with xmodmap but it's error-prone and complex. Since I'd like to change another couple things I was looking for a simpler workflow.
A search seems to point to gnome-tweaks or system settings, but they seem changed compared to - for example - 18.04 and I cannot find a keyboard-mapping section in either.
I'd like to avoid having to change things in xkb - seems a bit too complex and risky.

It sounds to me as if you want to explore Tweaks -> Keyboard & Mouse -> Additional Layout Options.
To get an overview of available XKB options, you may want to run
man xkeyboard-configand scroll downwards to OPTIONS.
You may be intersted in the Kay-mapper gui
