Is my use case good for hugelkultur? Or should I throw my piles of old moldy/fungusy logs away?

I live in zone 4, with low drainage silty clay loam in a very flat area. The previous owners had large stacks of firewood, many of which are now at least 2 years out from having been cut, and starting to rot with clear fungus activity. There are logs with multiple different kinds of fungus visibly growing. Rather than throw these logs away, I have been thinking about semi-submerged hugelkultur as a way to grow some things with better drainage and put this rotted wood to good use. Not a full mound, but just digging down about 6 inches, and then using a 8-12 inch layer of logs, followed by compost top soil, probably getting me to about 1.5 feet off the ground. This will be for small scale home gardening: at least some tomatoes, onions, garlic, peas, squash, and herbs.

I know that many people say hugelkultur isn’t a one-size fits all solution, but I am wondering if it sounds like a good fit for my situation? Or should i just grow in the ground and throw the logs away?
