Might be worth checking if they will do the 60 day extension because of Covid instead of family. That way you still have your family extension in 'reserve' you know, just in case 😉
Of course it goes without saying all offices are different, however this was my recent experience. I was actually suggested by Ubon Ratchathani not to waste my 60 day family extension at the moment. Due to them currently being able to offer 60 day extensions without the need for an Embassy letter that is the better offer. And if you return before the end of November, they can issue another. Then you can save your 60 day family extension for a later date.
The officers exact words were 'we are here to help you'
