Overall, yes. I find it helpful to think about sexual and romantic attraction as being things I don't experience. When I want to hug or cuddle with someone, I find it helpful to think about that as sensual attraction. However, aesthetic "feelings" don't really seem like attraction (at least as I experience them). My attraction usually leads me to pursue or want to pursue a specific course of action, but that's not the case with aesthetic. I might admire someone's appearance, but I won't go out of my way to look at them (or keep looking at them if they move out of my line of sight), just like how I might enjoy looking at a pretty picture but not act on any impulses or anything.
Sometimes yes and sometimes no. When I'm friends with someone I have a squish on, there's definitely an attractive element, in that I'll consciously and unconsciously try to spend more time with them, text them more, etc. Sometimes this can coexist with sensual attraction but it doesn't have to, and when we're not interacting, I'll often times be wishing we were interacting more. When I have a squish on someone I'm not friends with, it's more of a feeling of wanting to be friends with them, but without any specific action. There's a sense of wanting to hang out, but it's different from a squish on a friend because, in this case, it's hanging out to have a friendship develop on its own, and if we don't end up hanging out by coincidence or if the friendship just doesn't develop, nothing really happens, I easily forget about the squish, and the feelings go away.
Maybe the guarantee or lack of guarantee of a positive outcome if I follow though with certain actions, and the specificity of the actions in question? For a "feeling"/unfriended squish, I don't know for certain that I'll actually enjoy hanging out with the person in question, it's just a guess my brain decided to make. The action I'm interested in pursuing is similarly vague, just a nebulous desire to hang out with them somehow. For an "attraction"/friended squish, I do know that I'll enjoy their company, and I have specific things I want to do with them. (Or rather, there are lots of specific things that I know would make me happy, but as long as they involve interaction, I don't really care that much)
