The biggest ones to avoid are psychedelics/hallucinogens; the reasons for this should be glaringly obvious.
Others IMHO would be dissociatives (which I honestly see as little different to psychedelics), and amphetamine-type stimulants (which are notorious for triggering panic attacks and paranoid/delusional thoughts, even in healthy individuals, and are likely to wreak complete havoc on someone who's already fragile and predisposed to it). Note that I'm talking really only about amphetamine/PEA derived stims (Adderall, Ritalin, meth, phenidates, cathinones, phenmetrazines, etc), stims with different mechanisms of action (caffeine, *-afinil, nicotine) should be okay (in moderation).
Benzos and alcohol can trigger anxiety in some, but if they don't for you then I don't see the harm, in fact benzos are sometimes prescribed PRN to schiz/bipolar 1 patients. There is obviously a risk of addiction, but in practice as long as you use them responsibly the worst of it should be mitigated (relatively; don't forget that the antidepressants and antipsychotics they prescribe for schizophrenia also induce a physical dependence in the long term, often as powerfully as benzos).
