Sadly yes, rvpiano, you will need a PC or a laptop. Most laptops and PCs these days don’t have CD drives in them so you also need to buy a USB CD drive. These are fairly inexpensive, around $30. Perhaps you could borrow a laptop from someone. dbPowerAmp is great software but the free Exact Audio Copy works well too. I use a shareware program called mp3tag to snag cover art, album name, track names, and year of production, and add it in the metadata automatically. It finds stuff really well about 80% of the time. Note that .wav files never had the metadata header in them for holding cover art, but you could rip to lossless FLAC or ALAC and they both can contain the metadata for artwork, album name, track name, etc. Do be aware that ripping CDs can be time consuming.
My nephew conned one of his kids into doing it when they were 13 years old, offering them 10 cents for each CD they ripped. I think they felt ripped off. LOL.
Good luck. Long ago I ripped about 1300 CDs into iTunes and will never do that again. It took me a few months doing a few each night.
Another possibility if you don’t want to do it yourself is to make a deal with someone who does have a PC and pay them say a dollar a CD or so then simply get the data files from them.
I’d take a little time and properly clean the CDs before ripping them to help with any error correction. Note if you use iTunes make sure to check the checkbox for "Use Error Correction when reading CDs" in the Import Settings.
Finally, back up those data files in at least two locations for safety. Hardware can fail at any time. Oh and for your use case, that Brennan Helix recommended above by kingbr looks interesting.
