To a large degree it's going to come down to personal preferences. There are a lot of good choices in that budget range.
The CZ-75, Glock, S&W M&P, FNP, SIG, Ruger, and a plethora of other guns are all perfectly good firearms that would meet the basic criteria you mentioned.
Really hard to get too specific without going down a long checklist of things:
Do you want a polymer, alloy, or steel frame?
Do you prefer hammer-fired or striker-fired guns?
If hammer-fired, single action, double action, or double action only?
Do you care about magazine capacity (and if so, what's the minimum number of rounds you want)?
Do you want a thumb safety or not?
Do you want a magazine disconnect?
Do you want a loaded chamber indication?
Do you care if the gun is US manufactured or not?
Do you intend to spend close to your full budget or is that just an upper limit and you'd prefer to save money if you can without sacrificing quality?
And if the answer to most of the above is either "I don't know" or "I don't care", then I'd say to go ahead and get a Glock
. I don't even own one. I've shot them, but don't own one. They're very reliable and simple to operate.
