Two things I'd flag before you keep applying to networks, because I think the thread is solving the wrong problem.
First - awesomewebsites asked the important question and it got dropped. You said the content was AI initially, then rewritten. Four AdSense rejections at 3.5 months is almost certainly "low value content", and lightly rewritten AI is the classic trigger. That matters because Mediavine and Raptive have STRICTER editorial standards than AdSense, not looser. If AdSense won't take you, Journey/Raptive very likely won't either, and you'll burn weeks waiting on reviews to find that out. Ezoic and the smaller networks will approve you, but they approve almost anyone, which is why their RPMs are what they are.
Second, and this is the bigger point - do the maths on what you're chasing. 1k users a month is maybe 2-2.5k pageviews. Wedding is a decent display niche with US female traffic, call it $20-25 RPM if everything goes well. That's roughly $50 a month at the absolute ceiling. You're spending real effort trying to unlock fifty dollars.
Meanwhile you're sitting on genuinely one of the best affiliate audiences on the internet and treating it as a display inventory problem. 90% US, female, wedding, arriving from Pinterest with planning intent. These people are actively about to spend thousands of dollars, and they're in research mode when they land on you - which is the exact moment affiliate content works.
One dress, decor or registry conversion can beat a month of display. And the version I'd actually push at your traffic level: your own digital products. Printable planners, seating charts, budget spreadsheets, invitation templates. That audience buys those constantly, they're near 100% margin, and you keep the customer instead of renting them to an ad network for a $20 RPM. evergreen ads and PPCGrowthLab both pointed at affiliate and I think they're more right than the fifteen network recommendations.
Fix the content quality regardless though - not for AdSense, but because it caps everything downstream. Nobody buys a $200 dress off a recommendation from a page that reads like it was generated, and Pinterest traffic converts on trust more than most sources.
