Welcome to NGA, Italian1954!
The bigger the better, I think, assuming you intend to grow them to maturity IN the pots.
If you're just
starting the seeds in containers, both beans and radishes are easy to start by direct-sowing in their final growing place, so most people just do that.
For a big container, I would make most kinds of commercial potting soil both cheaper and faster-draining (better aerated) by mixing the potting soil with screened bark shreds (pine, fir or balsam, ideally).
I try to remove bark dust and fines smaller than 1/8th or 1/16th inch (2-3 mm). I also screen out chips bigger than 1/8th inch (nothing bigger than 3-4 mm). I'd add the bark fines to outdoor raised beds, and use the big chips as mulch (or grind them smaller with an electric lawnmower).
