I have a UHD monitor with a display port and two HDMI inputs. I have also recently ordered two FHD monitors that only have HDMI (no display port) inputs. Will most decent PC graphics cards (like a GeForce RTX 2060/2070/2080 Super) be compatible with this setup or do I need to look at getting something specific?

It's not difficult to find photos of ports on the GPU…
The packaging of the video card you buy will always list the port specifications. It can also be found on the manufacturer's web page…
eg https://www.gigabyte.com/au/Graphics-Card/GV-N206SGAMING-OC-…
DisplayPort is backward compatible with other interfaces, such as HDMI and DVI, through the use of either active or passive adapters. It's not difficult to find a passive cable from Amazon and use that if you don't have enough native HDMI ports.
Thank you. Is there a downside to running the two HDMI-only monitors off passive adapters from the GPU display port?
No.
Would I be much better off cancelling the order of these two HDMI monitors and looking for ones with display ports instead? So I can simply daisy chain all three monitors off the single GPU display port?
Not if you're running 1080 and 60hz. Use DP for the UHD.
So I guess I'm looking for either a graphics card with at least one display port and 2 HDMI ports, or else use one display port and two passive adapters to the HDMI on the two smaller monitors?
I guess a couple of these https://www.amazon.com.au/AmazonBasics-DisplayPort-HDMI-Cabl… look like they'll do the trick.
@Duckman: Reading into this a bit further, it seems as though I will likely need to use active adapters. I guess that's why these HDMI-only monitors were so cheap?
I use DP for my 27gl850 and HDMI for my second monitor ( depends on the main monitor you have )
I have three monitors though, so that's why I need to use an adapter. Or alternatively, swap the 2 FHD monitors I'm getting for ones that have displayport inputs, which would be more expensive, but by the time I spend money on adapters…
Do you need three monitors? otherwise, you can keep the QHD return one of the FHD? or Return both FHD get a better FHD
Which cpu and motherboard? You might able to run a monitor from the HDMI port on the motherboard.
I haven't purchased a CPU or motherboard yet. I'm looking at maybe the Ryzen 9 3900x but also considering waiting a few months…
Yes, most decent video cards from the last several years will handle this. The output ports will be listed in the specs of whatever card you buy.
The card might come with 2xDP 1xHDMI 1xDVI or similar. So you may need an adapter for DVI -> HDMI or similar. They are cheap and easy to come by.
I'm using a EVGA GTX 1070 like this.
check the outputs of the graphics card you want to buy. Some of the newer cards only have 1 HDMI
