I would be more worried about various , car or motorcycle rentals than those you have listed , it’s very common to take copies of your passport in many situations.
If you don’t feel comfortable giving them your passport to copy , do about 10 copies & carry them with you .
Visa agents may hold passports whilst things are pending for up to a week or more .
Yes Bangkok bank are freezing accounts and checking if all details match , if you are in Thailand you need to go into a branch update all details particularly phone & photo . I had to get a statement from my AIS with my address & passport number even though it’s been done before
