FWIW, cylinder bore wear is not linear. It compounds over miles. For example, if it wore the bore out 100 microns its first 40k miles, it wore the next 100 microns over the next 30k, then the next 20k, etc. So even if the bore is still in spec now, and you hone and re-ring it, you are at the tail end of its potentially useful life and you likely won't get another 100k out of it.

It sounds like you use it as a very causal cruiser. I'd certainly agree with some of the earlier suggestions to go through a good analysis of condition, if its decent then a very thorough tuning procedure to see if that net an increase you are happy with. If it does not and a rebuild is absolutely needed, then based on what you find inside, go with a minimal .010 or .020 overbore to leave as much material as possible.
