As an European, Classic Macs (and current ones) were just for arts/writting people. If you knew what CMYK was in order to print a newspaper, you were a Mac user.
I emulated Mac OS 7 under XP times, and i was impressed that you could get far faster speeds emulating the M68k (and partially the PPC) compared to Intel X86 without any hardware accelerating chip (IntelVT) or kernel modules trapping X86 instructions running it at native speeds.
I mean, PPC and M68k chips where much easier to emulate than X86 on itself.
On software, Classic Mac users can just resort to IRC and Gopher clients and visit the public https://bitlbee.org IRC servers in order to connect 'modern' accounts and being proxied to a Mac IRC client. And for Gopher, you have gopher://hngopher.com, gopher://magical.fish and the like.
Sadly you don't have an easy TLS library as Amiga users have (AmiSSL) where even modern web can work on it (and IRC over TLS, Gemini...).
Altough... if Amiga m68k emulators run fast with the Rosetta like tech for PPC... you would just fire up Workbench and then AmiSSL. Crude, but it would work. If not, here in the Apple subdir
you can get, maybe, some TLS enabled browsers:
Ardi Executor. There's a recent fork at GitHub. You can run m68k binaries seamlessly. You don't need propietary MacOS parts, just the software.
But if you are some software preserver, having a libre option to run legacy media it's always good for historical reasons. I am a daily libre software user but I emulate ancient machines with propietary stuff just for curiosity. As it not a personal computing device I find it fine. It's just an historical toy and not my computing device. And, well, if you want to create libre engines for old Mac games (ScummVM, SDL ports...), for sure you need to at least emulate the old OSes and run the propietary game in order to compare the output and correctness.
Also, it already exists "Mac" for x86. It was Rhapsody DR2 and it could run Classic Mac software and NeXT one too. It was like a blend of these two. OSX it's like NeXT Step concept 2.0, with few traces of Mac Classic.
Qemu will run it fine.
Rhapsody DR2 is not a solution for classic Mac OS on x86. Lunduke writes:

Another option is Advanced Mac Substitute. It doesn't run everything, but what it does run it runs really well. One of my goals is that you can use a 68K Mac application (e.g. MacPaint) as part of your personal computing workflow, if you wish.

Usenet will work fine without any TLS, and there's tons of content out there.
