Anglicans will, obviously, disagree with what I say here, and in fairness you should see what they say about it too [arrogant sounding remark]and then we can explain here why they’re wrong[/arrogant sounding remark] (That was a joke. Mostly.). What follows is my best attempt at explaining things from a Catholic perspective. As with most Catholic or not issues, it boils down to a question of authority, what that means, and who has it, but in more detail:
I think the short answer is that wanting a valid liturgy without having to “worry about the Pope and being called Catholic” is like wanting to go to the moon without having to worry about whether the rocket will launch or not, and without being called an astronaut. But the short version:
Christ founded a Church and entrusted it to the Apostles led by St. Peter under the guidance of the Holy Spirit. The bishops and the Pope are their successors. There have been a couple schisms, most notably with the Orthodox. But the Orthodox maintain the correct understanding of ordination, and so, while no longer under St. Peter, maintain Apostolic Succession (that is, their bishops are actually bishops in the sense of successors of the Apostles). They lack the same authority of the Catholic Church because they have separated themselves from it (not without help from some less than stellar Catholics at the time, I might add), but they maintain sacraments and are not terribly theologically separated from us.
But when the Anglicans split off, they so radically changed their ideas about the Mass and the priesthood that they no longer actually ordain validly - first, because they weren’t trying to do what ordination actually is, then because they did not have validly ordained bishops to do the ordaining. Lacking both bishops that are successors of the Apostles and the special guidance of the Holy Spirit that Christ promised to those successors in union with Peter, their theology has… wandered a bit recently.
Anglicanism also still has the basic authority/personal interpretation problem of Protestantism in general - though their bishops do lead them, they have in the recent past proclaimed contradictory things. What they profess now contradicts what they professed in the past, and there is no particular reason to think that this won’t continue - so we end up with an uncertain faith where there is no particular way for the person in the pew to determine if what their bishops are saying now is actually true or not, except to take his best guess. (Which is not, I think, what the Truth that will set us free is supposed to look like).
So yes, depending on which Anglican community he looks at, he may find one that looks kind of like Catholicism from a superficial external point of view. He may even find one that is reasonably close theologically on many issues. The primary differences lie in the question of authority and what exactly the priesthood is, I believe.
Examining theological issues makes sense, but picking a faith because it is liturgical and you like the ceremonies is like buying a house because you like the wallpaper. Not that the wallpaper isn’t important, but there are more important issues at hand. Again, the liturgy is extremely important, but it has this importance because it helps to reveal and bring us closer to the truth of the faith. Which is much more likely to occur if the liturgy is being celebrated in a Church that holds the true faith.
So I’d suggest that he find a faith that he thinks is true. Not wanting to worry about the Pope or being called Catholic is hiding from the truth. He needs to find out if the Pope is who he says, and if so then he should absolutely “worry” about him. As for worrying about being called Catholic… well, Christ had a thing or two to say about people who didn’t want to bear His name because of the inconvenience it could cause them. Best to worry about whether or not he should be Catholic, then let others call him what they like after he decides.
