I’m an atheist whose wife has encountered some of those same issues, going both directions… I’d caution against both clearing the plate and worrying much about what you were raised with. As per previous posts here, as well as in the experience of most of the highly rational folks I know...clearing the plate tends to clear off way way too much. In general, most of the old comes back later, and excessive plate clearing tends mostly towards intellectual/psychological drama.
I’d personally suggest that you worry less about the old positions you had...and look at where / who you want to be.
There are (in my eyes) better than even odds that this set of doubts is less valuable over time than your marriage, or even your extended circle of religious friends/family. Perhaps instead of trying to clear the table, you might instead look for areas of agreement between what you understand and your Christian faith.
All the best.
