New World Nutrition has clean, cheap protein. It won't take you to Flavor Town, but it is definitely drinkable. Mixes well, no clumps, and no extra garbage. There was a big deep dive on it on Reddit. I am a lightweight at 180# and also go with the 1g/pound convention. Somewhere between 180g and 300g it gets too much, and I will start burning it, leading to me smelling ammonia during my workouts.
I use this one, specifically, but they have others:

Another product I use is Humapro. It sounds like a bunch of marketing hype, but I swear it actually does work. I added it in when I was in a hard deficit where I kept showing muscle loss with every Inbody scan. When I added in the Humapro, the trend stopped and actually reversed a bit. If I had added in the food needed to get an equivalent amount of (claimed) protein, it would have shrunk my deficit quite a bit.
