I wouldn't actually SOAK seeds in a dish of water or peroxide for more than a day or much less than overnight, just because I haven't read about other people soaking them for days.
Someone suggested it to me for old salvia seeds, and it made a big difference.
I was actually thinking to
keep the germination medium damp with weak peroxide , as some people suggest chamomile tea or cinnamon. But peroxide actually seems to get some seeds to "pop" faster.
But peroxide ought to supply a little extra oxygen, and discourage some decay organisms, either during an overnight deep soak or while sitting on coffee filters or in sterile seed-starting mix.
I usually killed seeds by drowning them until I started using very fast-draining mix.
I also mitigate my overwatering compulsion by keeping an absorbent pad under my tray of cells, so I can bottom-water without flooding anything. I just keep the pad damp, and that keeps the bottom layer of soil mix damp in every cell.

P.S. Have you ever tried starting peas in a length of guttering, maybe in a greenhouse or under plastic film? That gets them going earlier, and you can push the pea seedlings out of the guttering into a trench 8-16 inches at a time.
