I personally would set it up in Google Search Console for each subdomain and experiment to see how deep Google matches subdomains on subdomains. And do 302 redirects (https://first.steps.for.planning.wedding https://first.steps.for.planning.wedding ==> https://planning.wedding/first-steps https://planning.wedding/first-steps) Although I'm not sure what I'd do on https://for.planning.wedding https://for.planning.wedding, but probably a 302 to https://planning.wedding https://planning.wedding The nerd in me would then automate any slug that ends in "planning wedding", set up the domain in Search Console and ensure its verified properly. For the record, I really like this branding idea.
