Yes, the theme looks nice. And with the Block Editor it will be flexible for sure, at least within the world of blocks.

However, it is not the only one, others like GeneratePress, Astra are also fully supporting Block Editor, Classic Editor, even Page Builders. Those for example are also somewhat like “frameworks” in offering lots of filters, hooks and are developer friendly.

Having a pro upsell like GeneratePress and Astra and some others do, doesn’t make those themes bad at all.

Not all “upsell themes” are equal. There a lot of differences, same like the “without upsell free” themes.

And yes, the theme repo search and filter was always bad, really bad. Users complain about this for the last 10 years or so. I have given up my hope on this. It’s a mess.
