Only water for me 98% of the time. Sometimes, if I want something with some flavour, I'll have a soda sweetened with stevia, but that's rare. I don't drink alcohol, so other than water, it's black drip coffee or espresso for me. Half a glass of red wine twice a year with my dad; at Easter and Christmas dinner and I still have beer in the fridge from January 2020.
I can't remember if I read it on BITOG or not, but recently, there was an article suggesting that water during meals actually dilutes the meals nutritional values.
