What to do with a $2m/year Ecommerce website? I

I had a pretty successful ecom website from 2010-2020. Its best year did $2m gross sales. Around 100k products listed on my site. 2020/covid hit and all my suppliers had no inventory. I was canceling 75/100 orders every day. I ended up putting every single item out of stock. I was kind of ready to move on with this business anyway. The business was dying. Covid just killed it. Now amazon seller just kills my margins. I threw up a bunch of ads...completely cannibalized the website to just earn $500/m in adsense. How can I utilize this website? Should I keep it up? Should I add a bunch of AI SEO? I have all the products still up...just out of stock. Should I add a blog of related items and just include affiliate links? The domain has fairly high authority with google.
