When editing/studying many of the buttons do have keyboard shortcuts.
Here is the group that will be added to my preset (should be online in two weeks or so, have some tiny bugs I need to chase down).
(Group when studying cards)
(Group when making cards)
Both of the groups are CAG so they pop up depending on what you are doing.
I did not find a way yet to show your decks in the TouchBar though…
I though used some Add-ons for Anki such as "Customize Keyboard Shortcuts" (24411424) or "Mini Format Pack" (295889520) and modified them a little bit.
