Magento 2.3 PHP 7 Version – Quick Question

I just used multiphpmanager to go from php 7.2 to 7.3 after reading it will run on the newer version, but when I refreshed the page, the site threw an error, so I switched it back and it works again.

Maybe I already know the answer to this, but would like to confirm. Do I need to reindex and refresh cache after switching the php version, or is there something else needing to be done first?
