As with all things aviation - you can ask 10 people a question and get 11 answers (12 now :P). As everyone has their own 'style' on a subject. The key is to find one that is correct, consistent and SOP.
I'll preface the following with - this is only my tip - not a replacement of FCTM guidance or company trainer input.
The main point of where to look is to gauge some form of depth perception / closure rate to make a decision on when to flare. It is a visual maneuver always but the rad alt cadence callout offer a decent secondary guide.
The flare is an attitude change to reduce the ROD (not eliminate) until touchdown.
The landing flare is a few seconds of flight - no big deal.
Is it useless to look far away? It depends.
Looking at the touch down point gives little depth perception / closure rate - but in the same vein looking arbitrarily at the end of the runway can also offer little depth perception / closure rate.
Find what works for you (runways can in all shapes and sizes length and width - so end of runway isn't always consistent)
With experience you enter the "unconscious competency" stage where you don't really think about applying the above, it just happens (similar to gear changing in a car from your first driving lesson to passing your test)
