In the player collecting world, this is something we all have to face eventually.
When it comes to your Bobby Ryan PC, I would say look for other ways to expand the PC if you can get enjoyment out of that. Jersey swatch variations, Graded cards, oddball stuff, a Ryan card project or print run % you'd really like to hit of a favourite serial numbered card, collecting jersey #'d cards, etc. There are so many ways to build up a "collection within a collection" so to speak. I have done this for my Enroth collection at various points over the past 14 years and it has paid off.
My player hasn't had as many cards produced as some other of the superstars /main-stays out there, so maybe I have had more time to think about this topic more often than other collectors I suppose.
Among the sub-categories listed above, I have also found enjoyment for collecting cameo cards as well. It is a very small and quirky portion of my player collection that is not everyone's cup of tea, but it was something that I was introduced to years ago through another member on these forums and it just goes to show you that aside from the checklist-heavy releases we've all faced over the years, there are still many ways to build out a player collection even after the music has stopped and/or their career is slowly coming to a close.
Best of luck moving forward. There is no wrong answer and you have all the time in the world to expand your collection as you see fit and when - That is part of the luxury of your PC player not getting as many cards, as it allows you to take a much-needed breather, appreciate what you have, and start laying the groundwork for what's to come next in your player collection journey.
Also, make it fun. It is our hobby after all.
