Well yes it highly varied. However Romans were generally more motivated by plunder and subsequent economic exploitation. To an extent they didn’t really suppress local cultural practices or imposed forced assimilation in cases where it didn’t conflict with that and even often allowed alternative power structures to exist. Assimilation largely happened over time and was mostly voluntary. To be fair gradual voluntary conversion to Islam to enhance your social/economic status was the main mechanism in the Muslim empires as well. However in Rome the transition wasn’t as binary and “multiculturalism” was much more tolerated. Also Romans were way more open to integrating and assimilating foreign cultures and practices (which is why the Roman Empire eventually turned into a “Greek Empire”) what being a “Roman” meant was way more malleable and flexible than being a Muslim.
