Mechanical Keyboards

Hello friends. I am new to the mechanical keyboard world. I purchased my first, a Keychron K5 Pro. I love it. Feels great, works great, sounds great. I would like to replace a handful of the keycaps however, trying to just customize a bit.

So my issue: I can't figure out what to buy. The K5 came with "Low-profile Double-shot PBT Keycaps". They measure about 4mm in height (just the keycaps). I'm looking for a handful of 1U caps, either in some fun colors or with random art printed on them. I am not opposed to getting a full set of keys if they are priced right.

From what I am reading in random places, XDA or DSA profile caps are CLOSE to what I have in size and shape. Can anyone guide me here? Maybe suggest a specific seller or a better search term than "Low Profile PBT Keycaps"? I seem to be finding a lot in other profiles (I get it, I purchased a kind of specific keyboard type), but not a ton of caps that seem to be correct for me.

Please help! Thanks in advance homies.
