Did they ever even mention the Beta Quadrant in Voyager?

The fact you can't produce evidence of what went on there is kind of proof that it got the odd mention but was not part of the narrative really.

The Beta Quadrant includes the entirety of Klingon and Romulan space and half the Federation. Earth spends half of every year in Beta and half in Alpha (which might be part of the point of having the quadrant dividing plane pass through the primary star of the Federation's capital world, to make it more egalitarian). So we've seen a ton of stuff that happened in the Beta Quadrant; it's just irrelevant to talk about quadrant designations in most contexts. After all, you don't see a lot of stories set in England or France where characters talk about which side of the Greenwich Meridian they're on.

it's just irrelevant to talk about quadrant designations in most contexts.

Ergo it isn't typically addressed.

They talk about quadrants more when it's a counterpoint.

i.e. gamma quadrant - the one all the other side of the wormhole.
delta quadrant - Voyager is lost there.

The original series told us that the Enterprise travelled all over the galaxy. Through it's centre and to the limits of interstellar space and the galactic barrier itself. Later shows told us that it was just one large area it travelled so who is right? Fans of TOS or Trek in particular?

I agree it was barely addressed at all. It’s weird that it seems the Klingons and Romulans were (in canon?) located mostly within the BQ but in DS9 all the references to them acting together were to the Alpha Quadrant alliance.

I think Sulu and the Excelsior were also meant to be returning from the BQ in The Undiscovered Country.

That's because DS9 had established "Alpha Quadrant" to mean the Federation side of the Bajoran wormhole, and it was simpler to use that term for everything on our side of the wormhole instead of complicating things by adding another quadrant to the mix. Making things clear for the audience and avoiding unnecessary distractions in the narrative are higher priorities than strict worldbuilding accuracy.

As I've said before, though, it's no weirder than the way we call Europe "the West" even though most of it is in the Eastern Hemisphere.
