I also dropped strava a while ago. For me it was because they updated their privacy policy to blanket allow ai training with your data to both strava and any partners. They claimed it was only for XYZ but the privacy policy allowed it for any use which i consider dangerous for health and geospatial related data without specific, informed consent.
But for alternatives, when i was into cycling/triathlons i used golden cheetah extensively. It's UI takes some getting used but ime it was more powerful than anything else once you got used to it. I used it as a strava premium/trainingpeaks premium alternative and had multiple athletes (me+coaching) in there.
This is what i do. Have certbot running every night, and it'll auto skip if it is too soon to renew. If renew is successful then it'll deploy. Pretty much set and forget it.
