Hello there ! Some years ago I decided to do the same as you do, i.e. getting a good monitor for graphic design (print) and photography editing.
I've done a lot of research and there's a lot of professional monitors, but I was looking for something affordable and practical (a good monitor foot that can rotate the monitor easily).
You have to decide either you will perform a manual color calibration after purchasing the monitor, or if you are looking to get a factory calibrated monitor.
I depends also on what you plan on doing with your edited photos and videos :
If it's mainly photos that you want to process, and then you want to print them, then you might need to get a calibration device to match perfectly with the printer you'll be using.
On the other hand, if you plan on taking videos, editing them, and then posting them on the internet, consider the following : almost everybody watching your video won't see the same thing as you do ! Because they all have different monitors, color, brightness, contract and such will be different for them (can be slightly, or really crappy).
So in this case, calibration with a device isn't really necessary, and you should only get a good factory calibrated monitor.
Not everyone will see the difference on internet, but at least you'll have good colors to work on !
And if it's needed for a professional use, you'll still be able to provide good quality work.
I'm using the Asus ProArt series at home, and I have 3 of them in a multi-monitor setup : 1x PA238Q and 2x PA248Q, which are 24" monitors, with IPS panel.
The calibration is almost always good out of the box with these series, but you'll be free to search more infos on that on the net.
I'm sure there is plenty of other monitors that could be as great as they are !
Also, I agree with FlyGary and you might also consider upgrading your hardware if you haven't done it already.
To do some video editing and exporting, my advice would be to have at least a good intel i5 or i7, and at least 16gb of ram (especially if you plan of using 4k videos, those are heavy to process).
Also, having a good graphic card is essential, as far as a lot of editing software now uses CUDA to export or process video. Graphics cards are needed in any case to preview/play/edit videos and images smoothly. To give you an example, I'm working with an i7 6700k with 32gb DDR4, and a GTX 980 - which is quite a good build - but sometimes I still have some lagging/slowing issues when reading or editing full 4k videos !
Good luck in your search !
