My understanding is that the anabolic window may or may not be a thing depending on the source, but with how digestion works, you can't really line up the moment absorption with said window. I believe there are some studies out there showing that the timing of eating pre vs. post workout didn't have a large impact on muscle gain as opposed to just making sure you're getting enough calories and protein on a daily basis.
Pretty much this. I believe the general consensus is that at a small timescale, nutrient timing may have some effect, but at long timescales where it really matters for body composition, a small caloric surplus and adequate protein intake are all that are needed to reliably build muscle when resistance training.
