Fall cover crop?

I planted red clover as a fall cover crop last fall in my raised beds. I have been getting more interested in the benefits of manure crops for my garden and, recently retired, I now have the time to pursue it. Do you have a recommendation for a fall cover crop for here in the valley? I saw a seed mix for f clover, rye and buckwheat and wasn’t sure if that was a good cover. Reading up on buckwheat, I am interested to try that next. Thanks for your thoughts.

Small worms in potted lime a problem

I watered a potted lime after stirring the soil to mix in fertilizer, and about a dozen small worms 1 1/2 to 2 inches long with a very pronounced pink translucent front ends came out of the soil. Photo attached. Are these potentially pests? Or neutral? Or beneficial? They are very consistent in size and do not look like other earthworms from the garden. They are either all the same size because they are very young or a different species than I’m used to seeing in the garden.
