What do you primarily want to shoot? IDK about cannons but Nikons 18-55 is actually a great lens optically just not fast enough for low light, i’d imagine cannons kit lens would be a pretty decent one as well.
Aside from when what I’m photographing calls for it. I pretty much use my 35MM for most everything. (35MM Lens on crop format like mine and your camera is equivalant to a 50mm lens on a full frame, your 50mm is actually closer to 70MM I believe)
I pretty much use my 35MM 1.8 and my Tamron 35-105 F2.8. When I pick it up i’ll probably be using the 11-16 and my 35-105 f2.8
