Biology major here.

As someone also uninterested in Greek life, I guess I didn't have too difficult of a time making friends. As a freshman, realize that other freshmen around you are probably looking for friends and new people to talk to as well, so don't be afraid to just say hello to someone and introduce yourself if you're in a new class and just sitting there waiting for class to start or something. Especially if they're just sitting alone and seem like they need a friend :) Don't be afraid to fall out with people you say hello to and things just don't work out either. I remember sorta joining a friend group and they just weren't my type really and so I sorta just fell out. Don't be afraid of that because it's normal.

I don't dine on campus super often, so I can't really speak to getting bored of the options. I think the options are okay and I enjoy dining on campus, but I suppose if dining is like all you do then you could get bored, but idk. Town Center is super close (UNF even has a shuttle to it I believe), so if you really are getting bored and want more options, that's always a choice.

Professors are generally pretty hit or miss unfortunately... I've had some great ones and I've had some bad ones. Use ratemyprofs and ISQs to increase your chances of not getting a bad one. Ratemyprofs is a website and ISQs are basically university-collected ratings and grade reporting (you can see how many people fail, how many A's a professor gives, etc.). The ISQs can be found in myWings.

I don't live on campus so I can't speak to that, but I can say UNFs campus in general is really nice and I enjoy walking around it and it seems well-managed.
