Exact Match Domain - Rank and Redirect?

I run a high-ticket ecommerce store selling home fitness products and I've bought 2x EMDs for keywords at have around 1.5k - 4k SV and are highly transactional within my niche.

I'm unsure how best to utilize these and I'd like peoples thoughts on if any of the following would be good options:

1. Redirect URL straight to my main store (probably very low impact)
2. Setup a wordpress blog, get it indexing and then redirect to my store (Doubt it will rank well as most sites in the SERPS for these keywords are ecom stores)
3. Setup a wordpress blog, use as a PBN and link on the homepage to my store (No links to the new EDM so probably low impact)
4. Setup Shopify stores on these domains with all my products and then later on redirect them once they're ranking (expensive & time consuming + no links so will it rank?)

I'd be interested to see what would be the best option, or if there are any other good uses for EMDs?

Perhaps built out the site and get directory etc. backlinks, leveraging the effect of EMD domains that even at those many places where only the site URL is available as link anchor you still get your keywords into the anchor text.


Then after a good while 301 it, maybe even with a press release stating that your company proudly merged with / took over EMD-Domain company. To make it safer and longer lasting. (I've read about this "Expired domains: make takeover official" technique somewhere)
