This isn't strictly an answer, but I've come across much the same issue being here for about a month (after using SO for a few years). So I'm probably a good use-case.
I find it rather addictive to review other posts, but where I don't know if the post is applicable/accurate with regard to a particular subject I'll always skip it rather than upvote by default - that's just too easy and some just don't make the effort.
If anything, and where applicable, I'm more likely to correct grammar or fix layout/markdown failures, improve readability and hit I'm Done as my way of contributing.
What I do know is that posts are often well thought out, well structured and provide what I consider good effort - but, much like you, I can't accept/upvote them from a compliance perspective - I don't think it's a good idea to do so! From a personal perspective it's better to just skip and leave for those better experienced in a particular field - which I find myself doing on a regular basis.
I don't think a compliance-tick would be constructive, despite it's draw. Sure there could be a "looks good" button, but then domain experts could think it's utter rubbish.
Despite all my skips to date, I've never seen the first post queue beyond 20-30.
