If PCIe is the only internal option I believe this is correct. Most 'onboard audio' (which is also HDA) is Realtek codecs, but not all systems have those (or they may not work, or work well, etc). If PCI is available, VIA's Envy24 chipsets work really well too (M-Audio is probably the most popular/common option for those, but there were other OEMs that used VIA (I believe Chaintech did, for example)).
USB of course should be more or less universal to modern PCs, so that's also an option, but it requires a class compliant 'USB Audio' device (there are relatively older 'USB soundcards' that are not actually class-compliant, like a lot of the early Creative USB Sound Blasters (e.g. Extigy)).

I've heard of higher sampling rates(192Khz) with usb. Is that a regular thing?

With USB Audio Class 2.0 yes you can do all sorts of very high sample rate (even beyond 192kHz), DoP, DXD, etc - linux natively supports this for a while (I don't know which kernel brought it in, its not bleeding-edge though), as does OS X/macOS, but Windows does not, so not all devices are Class 2.0 (this is different than 'USB 2.0'). Standard 'USB Audio 1.0' is limited to 16/48; I don't know what the upper limit is for 2.0 but I've seen some devices advertise 24/352 support (!). DoP requires specific player support, and I'm not sure what on linux can play it (a quick web search found this:
https://www.rollofone.com/?p=309).
On add-in soundcards (PCI and PCIe alike) the upper limit tends to be 24/96 or 24/192 depending on the device - for example I believe CMI8788 can do 24/192, and some of the VIA Envy chipsets can as well, but a lot of the Creative cards only do up to 24/96. The big 'gotcha' is that many of these are doing that in 5.1 or 7.1, as opposed to stereo-only on USB.
