Yes git restore and git switch were made specifically to be simplified, more specific commands which are safe from performing destructive actions without warning. They were implemented in Git 2.23.0 in 2019.

2019, so 4-5 years ago so not that recent but not ancient either. But unfortunately tutorials have not been updated.

I would say that the biggest benefit of git switch is that you can't switch to a detached state without using a flag (--detached or -d). If you do git co $tag or git co $sha-1 you may get at one point the error “you are in a detached state” which is ununderstable for begginers. To get the same error with git switch you must explicitely use git switch --detached $tag/$sha-1 which makes it much easier to understand and remember that you are going to do something unusual.

More generally it's harder to misuse git switch/git restore. And it's easier to explain them since the only do one thing (unlike git checkout which is a mess !).

So if it's only for you git checkout is fine, but I would still advice to use git switch and git restore so you will have an easier time to teach/help begginers.
