What's the best oral antibiotic for perioral dermatitis?

Culture of Medicine. This is not how medicine works. There are so many variables that go into choosing the appropriate antibiotic for an individual patient. There is no such list as the 'best' antibiotic until the patient variables are taken into account.
Antibiotic = Poison. Anti=against, bio=life, tic=a thing or compound. I.E. Antibiotics are poisons, poisons which make certain cells sick or die, yet typically do not bother us. Over the decades since sulfa agents, then penicillin, etc. Were discovered, researchers have only discovered 8 classes total, the reason for increasing concern that we are loosing tools. Once ab has killed what is sensitive, no longer useful.
