exactly this.
the absolute most important factor is total calories adjusted for wanting to gain/lose/maintain. .8g/lb is somewhere in the middle of what science suggests (and just a hair above what you eat), so using that to get an idea of protein intake is a good next step. after that it's all about doing whatever helps you abide by that total calorie intake. if you prefer eating a bit more protein that is fine, but at the same time if the idea of more eggs or such makes you nauseous then eating something else instead is also fine.
it's just a case of big rocks and small rocks. total calories, a base protein amount, and some kind of regular exercise are the big rocks. going from .8 g/lb of protein to 1.1 g/lb is a little rock. focus should be on the former.
someone, sometime, arbitrarily came up with 1g/lb and the masses just ran with it, now even recommending more than that. problem is none of the actual science backs it up, but instead suggests that anything from .6ish g/lb is sufficient but over 1 g/lb is unnecessary.
in other words: ^^ that
