Generally speaking for a system like that I think a decent 1440p is probably the best choice. You'll definitely want some form of higher refresh rate basically 120Hz+ and variable refresh rate (Freesync for AMD though some will also carry G-sync compatible) can be a nice bonus as well.
Each panel type can have advantages and this is accurate for equal quality monitors:
Colors: IPS > VA > TN
Black: VA > IPS > TN
Response time: TN > VA > IPS
Price: TN > VA == IPS
Most common disadvantages:
TN: Pretty much every monitor these days has poor colors and blacks with the only reason to buy them is really high refresh rates (and sometimes high refresh on a budget).
IPS: A lot of the screens will have what's referred to as IPS glow which is basically backlight bleeding and this varies from monitor to monitor. The response times usually aren't quite as good as VA and the black levels will never match VA.
VA: The colors won't be as vibrant as an IPS display and almost all of them have some level of black smearing due to pixel transition. Optimal refresh rate and overdrive settings can minimize this and it hasn't been a problem for me with the display I've been using for a few years.
This is a recent video which talks about 1080p vs 1440p, why it's a good time to go ahead with 1440p with some generalized buying advice. They have a bunch of good review/explanation videos this is just a more generic informational piece:
