Good to hear you used some of the Marriagebuilder items.

However, to be compatible there has to be a lot more than just common everyday interests. There are other things that a lot more deep rooted - i.e. moral values, the infamous "boundaries" our C keeps talking about, religious/spiritual and/or political views - just to name a few.
That is a starting list for sure. It might be a short list. It might be a long list. All I know is is not much or what to do some days.

we are empty nesters
Same here. Our kids are 34 and 36. Sometimes I feel they were enough glue to keep us headed in a similar direction. There is also a certain amount of bonding after 39 years of M. Our shared interests area is weak.

for the most part I can work around our differences
That is good to hear.

I'm off to do a service call.
