Coros training plans

I started running 7 months ago and have been into strength training for a while before then. Currently, I've done a few 20 km runs as part of long runs around 6:30/km pace but I've not yet run in a HM "event". I recently got a Coros Pace 4 and I believe I can benefit from the training plans they have. I'm confused as to what training plan to follow. They have a sub-2 HM training plan (which is currently my goal), intermediate HM plans based on both pace and HR etc.

1. Can someone guide on which plan to choose and if they're good?
2. Most of these plans don't have strength training included in them? Is there a way I can include them or combine a running and a strength training plan? Also to include some cycling cross-training.
