Can I use adapted lenses on the canon eos 77d?
I don't cover adapting lenses from other mounts, so I can't tell you how well that works on the 77D. What I can tell you is that the 77D takes Canon EF mount lenses natively, and the full list is on its Canon EOS 77D page. That includes EF-S lenses, and third-party lenses from Tamron, Sigma and Laowa.
If you want a sensible all-rounder, the Canon EF 24-70mm f/4L IS USM is a good pick. For wide landscapes, the Canon EF-S 10-22mm f/3.5-4.5 USM covers a lot. The 77D has no in-body stabilisation, so stabilised lenses help at slow shutter speeds.
For how the mount works, see Canon EF.
