>>4318646It's tricky, but get something you can afford, that you don't mind carrying with you, and preferably a sharp prime lens, like a 50 1.8 or a 35 1.8 to start with
DSLR or Mirrorless doesn't matter, but i've found with friends getting into photography, you either learn to use an OVF and gauge light in the scene yourself, or you get chained to live view and the camera handling everything for you to a larger degree.
Used late model canons, like 5D MkIVs, or the 6D MkII would be good if you went dslr and didn't mind size, for mirrorless, look at things like the Z50 from Nikon, the Fuji XT 30 and 50 seties, or perhaps Olympus options. Just remember that glass is often more important than sensors and so on, so whatever system you choose, make sure you can get decent access to other lenses and so on as you build up your skillset and hone in on what you like using.
Best of luck OP!
