Ken, I noticed that in your growlist, you don't have droseras yet, I suggest you try them, specially the Annuals (if your conditions allow), they should give you flowers easily
I have been a bit lucky because one of my newly purchased VFTs had a flower stalk, I cut it off, then another one came out, so I decided to let it flower and try to get seeds, I got maybe a few, but not sure if they are viable. Did it just for the heck of it.
When I got some plants from TriffidPark Aus, VFTs, etc. the plants were not so happy from being bare rooted, but after 2 weeks they bounced back and maybe 5 VFTs had flowerstalks, and 2 Sarracenias. I however cut them off because I felt they were still weak from the trip and still acclimitizing.
All the flowerstalks were not thrown away though, coz I read the same idea that they can be used as cuttings like leaf cuttings. Some of them are still sitting there.
I do have a Capensis plantlet from a flowerstalk now, but it is still fragile.
For Droseras, I'd say D. Capensis, D. Spatulata, D. Burmanii are great candidates for getting them to flower and get seeds. Plus I feel that they don't get stressed from flowering. Heck my D. Spatulatas are still flowering now.
Good luck!
