I searched and was surprised to not find this topic. I am looking for fics where Buffy see the value in Anya. Can be any length or genre but I prefer completed fics.

It's not really the main point of the fic but A Pirate's Life for Me by Addie Logan has Buffy turning to Anya for advice after getting stuck in a supernatural romance novel with Spike. I know there are others that I've read, particularly those where Buffy begins to see Xander's prejudice towards demons. I'll try to think of more.

This also may not be quite what you're looking for, but coalitiongirl (here on SR)
has a story where Buffy is put into Anya's body (think it was
time travel as well?) and has to convince everyone to listen to her, hence
touching on the subject of others not listening to Anya.

I'm on my phone so I can't go look up the name of the fic (sorry!), but I
remember that the summary is fairly self-explanatory and you should
have no problem finding it.

I'll take a look when I get home for some others, too

A Stitch in Time. . . is coalitiongirl's story. It's here and on EF -- might even be on the BSV as well.

The Time of the Guardians by JackOfSpikes
When A Slayer Cries by JackOfSpikes

maryperk's Dimension Series features Anya in a big important part. It's on this site but I usually read it at her site, Wicked Temptation. It's easier to find all the stories there in one place and it seems to be the most up to date.

Thanks so much for all the recs. Some I've read but some are new to me. I can't to read them all.
