They still wouldn’t be able to do very much. All an unlocked bootloader does is let you flash things via fastboot.
Even with a locked bootloader, you could still get into recovery and cause mischief with physical access. You wouldn’t be able to access the storage partition without decrypting it, but you could still maybe flash stuff to the system partition to infect it for the next time the phone is booted up.
Remote access to the phone won’t be able to do much of anything with an unlocked bootloader. The far bigger hazard is app signature spoofing (eg Magisk and MicroG), which if successfully exploited can cause all sorts of havok - you can have apps pretending to be other apps that have root access.
