Would love some opinions on pairing suggestions for a meal I'm making

Hi folks, for a good friend's bachelor party I was asked to make dinner for the group, and I'm doing chicken thigh tacos Al Pastor, with a tomatillo based salsa verde, corn salad, seasoned rice and guacamole as accompaniments.

I'd love to include wine options and my thought process is thus:

There's a good bit of fats in the guacamole, and somewhat in the chicken thighs. The Al Pastor marinade will be slightly spicy but really more smoky. All of this tells me acidity will be key, but perhaps not too much as the tomatillo salsa will have it's tartness.

There'll be some sweetness from the pineapple and corn as well, as well as plenty of savoury notes.

One of the responses may be Riesling, and that's probably not wrong. I wanted a red option as well. I know the traditional thought of red wine with chicken is Pinot noir, but I was thinking perhaps an aged (20+ years) Rioja?

Thoughts would be appreciated.
