Changing mind on marriage

My (34f) and boyfriend (31m) have been together since 2019 and living together since 2021 post pandemic as he worked for a place that has since closed and moved to my state and gain successful employment. I was very much against marriage when we first started dating as neither of us owned property and are renting, but now I’m looking to purchase a home and I’m wondering if we should just do the proper marriage so if anything happens to either of us, he will not have to fight family over property. We both have no children and have a life insurance policy on each other that covers salary for the year. I also have additional life insurance policy in my mother’s name as she is on my student loans. I feel pressured to marry him because his parents and mine are very religious and they don’t recognize us as a “real” couple, even to the point that unless we get a hotel, cannot sleep together in their homes. I of course respect that, but the side eyes and comments of “when are we getting married” are relentless as we’ve attended family weddings and they look at us if we are next, but we’re not. I know being his legal wife once we have real property will be a different matter, but I feel like we are fine how we are and will continue to make legal agreements as needed.

I’m happy and he’s happy where we are now, but should I ask for a ring?

Extra info: I don’t want children unless we adopt and he’s on the fence about it. We both make enough to be DINK and travel which is a big thing now since I have my passport now. His family and his family are very religious with him having close family being ordained, but we are non-religious.

Should we just have a legal ceremony? What are the benefits to being legally married (currently we’re both in good health, child free, and have health insurance through our jobs). I’m be happy just to have a religious ceremony to appease family, but he says it needs to all that or just nothing.
