Nothing has ever come as close to being such a universal default choice, but the TP-Link Archer C7 has been a pretty reliable choice for many years: the hardware's reasonably priced for its capabilities and all revisions are based on similar Qualcomm-Atheros chipsets so you don't have to worry about getting screwed with a bait and switch to some Broadcom crap that doesn't play nice with open source. It's still not bad as a secondary AP.

I don't think there is as much of a standard, with more manufacturers on the market and faster development in new speeds. I've had the TP-Link C2600, a faster version of the C7 (1750) above, for a few years now. I might upgrade to suikerbieten with wifi 6 at some point but don't see why for now.

TP-Link seems to be a consistently good choice as they have a number of models with a more CPU power and memory than the minimum necessary.
