I would say both; you can oppose the procession itself for all of its pomp and archaic tradition at a time where the country is dealing with a cost of living crisis and also have that also be more broadly a protest against the monarchy in general.
A large portion of the life of the royal family is public, even funded by the taxpayer, so to me it makes sense to allow for opposing viewpoints to be heard. Perhaps you can argue that a memorial service isn't the most appropriate time (though, I don't really subscribe to this viewpoint given just how much this memorial is rammed down our throats) to protest, I do think its where its likely to generate the most coverage. There is never going to be a more appropriate time to get people to listen
Edit: Just to clarify the point further - Not all of the arrests being discussed were made in Edinburgh (where the procession took place). Its debatable how much impact a person holding a blank sign in Oxford has on the events in Edinburgh (though I would wager its infinitesimally small). Equally, holding a sign with a swearword on it doesn't really "disrupt" in any meaningful sense either. A lot of people defend the police action on the grounds that it "may" have lead to violence via provocation and the person was arrested for "their own safety", but in that case why follow through with the charge? Rather than "de-arresting" (whatever that means) afterwards
