Yes, digital photos can be printed on archival paper; however, the processes to produce film and digital are different. By choice of film, developers, timing, and printing techniques, a film photo can be different from the same image produced via a computer and Lightroom, then scanned. There's a clear sense of personal satisfaction in the end results with film developing and printing.
I have Kodachromes dating back to 1939, and film negatives dating to 1941 - - and my Grandson has my old developing and printing stuff.
But, back to CDs: My somewhat extensive collection is 100% RedBook classical, and they spin quite nicely on a Bryston BCD-3. My grandchildren will inherit my CD collection and my 2 channel B ruston and Thiel system; meanwhile, I can contemplate the differences among several Verdi Requiem CD issue - - Reiner, Giulini and Barenboim.
