Same here. We only use ScotiaBank ATMs in POP, those are all indoors with a guard directly outside. Sometimes we've used La Nacional ATMs on the Beller due to cost saving, but those are not that private... Banco Popular used to have a nice rate for EUR/DOP conversion, but many times I have seen that ScotiaBank actually has a better rate... It does not compare to a casa de cambio or sending by WU, but still...
I might be paranoid, but I have also not used cards for any purchases the last decade or so in the DR... Actually, no, I used my debit card at BMCargo during the pandemic, but the way their POP branch operates, gave me confidence to do that and they did not disappoint me.
