CAJ, if you are using EAC and ending up with a FLAC file, you are introducing a third party software which could complicate things during your process, possibly.
I use FLAC sometimes, but I do it in two steps. Native WAV output for a "bit perfect" rip from a CD, then I convert WAV to other formats in a second operation if I need to.
I also use LAME, but hey, I have to put three hundred songs on my wife's little ear thingies she takes to work. I like being her hero.

Only times I've ever had trouble with the amount of time EAC takes to rip is if there are errors or built in errors to prevent copying.
CD players skip past these, sampling half a dozen times and just going with it.
EAC, trying to do its best, attempting to "lay it down" bit by bit, EAC sometimes runs into trouble with these errors.
I have had CDs that I could not rip using EAC, but resorting to Audacity or Winamp which ignore some of the imperfections, just like a CD player and just go with it, I have gotten rips that seem fine.
That always leaves me wondering where the imperfections lie that EAC could not find and fix.
I also use an older computer as a music server, with (varies) maybe six or eight hard drives connected to it, running XP with an MAudio card, but everything is turned off I don't need and it has never been connected to the internet to get MS involved again.
It works fine!
No Bluetooth, but I haven't really felt the need to use my system that way.
I can do cables.
If my daughter needs to cast something, we have a Roku connected to a Smart TV in the other room and that works fine for that.
You should talk some about these "Computer Professional" tweaks you have done. Don't know if I could follow, but some will, I'm sure.
