Does an external filter have to be underneath the tank or is it able to function just the same next to the tank?

Makes little to no difference for most setups, having it lower than tank will make it easier/quicker to prime as a siphon works better with a bigger head of water, once the filter is primed the shorter to pipework/hose the less the resistance to flow.

So minor pros and cons in most cases

That’s good to no, the filter ie Eheim 2213
 
Most external filters will have requirements like this.

Although the head of pressure in some ways is irrelevant IMO, as the same head of pressure will be on the inlet as the outlet so the pump should still work even with as say 50 meters head of water (ignoring the resistance of the hose/piping). But the head of pressure will relate to the pressure of water in the canister/filter can withstand without leaking/blowing a seal etc

I did give it some thought that if you had a CO2 reactor with a large head of pressure the CO2 uptake of the water could be pretty awesome, if I had a cellar I would give it a go but would need a pretty robust reactor to handle the extra pressure. maybe in next house - plus a lake and a bore hole for water so can do RO water, geothermal heating would be nice too..........

I've accidently blow the lids off my APS EF2 reactors turning the water on to fast when filling my tank a couple of times 🤣 it was all hands on deck for a few minutes :rolleyes:
