I'm confused -- you mention your own music is on CD (not LP) and you apparently consider this appropriately "audiophile" for your needs. Then you ask if "digital" files are just as good.
The thing to understand is that CDs are digital files. They are digitized at a 16 bit rate at 44.1 KHz. These digital files are simply stored on CD, just as if you bought a copy of Microsoft Excel on CD to install on your computer.
Downloaded and streamed files are also digital files, but just delivered over the internet and either played "live" (streaming) or stored on your computer's hard drive (downloaded.)
Streamed or downloaded files can come in a variety of formats from low bit rate MP3s, or CD quality (identical to what is on a CD), up to high-resolution files that are 24 bits, and up to 192 KHz, a much higher quality format than CD.
There are several streaming services that offer large music collections (tens of millions of songs) at CD quality and higher. I use Qobuz and have been very pleased with it. Tidal is another streaming service that is very popular with millions of songs.
