I'm pretty sure YouTube caps res at 1080 for most videos. So anything that shoots 1080p at 60fps is ideal and easy to edit(4k takes powerful computer)
I believe the t5 shoots only at 30 fps, but if your not to worried about quality it will work fine! Get a decent lens, or even just the kit lens will do.
Good luck!
Edit,. A good mic will help your quality the most! Especially with guitar videos. I would suggest the Rode Micro mic as it's cheap and decent quality(I have one).
But. The Canon t5 does not have a mic input so you will need an external way to record sound, then add it to the video later in post production. Zoom makes some decent external sound recorders
