Thanks again for the feedback DukeFleed. One last question, if I want to only change the name of an audio/subtitle track for a mkv file using mkvtoolnix, do I still have to choose multiplex?
Always.
That's not true. You can edit the Metadata of any track without remuxing.
In MKVToolnix GUI open the "Header editor" (third option on the left side bar) and drag and drop the file you want to edit. Simply open the track you want to change and select the field/flag you want to edit. It's probably not a good idea to mess with the Codec related metadata. But flags, language and track name can easily be changed to your preferences.
If you want to add or edit chapters, use the Chapter editor (fourth option on the left side bar).

Be aware that based on the speed of the drive and number of tracks inside the container, MKvToolnix can take some time to load the header information.

If you have multiple files with the same stucture and want to use batch processing, either get familiar with mkvpropedit and the console, or use JMKVPropedit.
It's also a good alternative to the Toolnix Header Editor, since you don't need to load the complete header information and simply tell mkvpropedit what to change, which is much faster.

Oh, I didn't know. I always remux now, even though I had some doubts, because in the past, many years ago when I started using Mkvtoolnix (2014) but then I hadn't used it for years, I remember not doing it in fact. With the new versions I no longer found how to do it and honestly didn't want to waste time. Anyway, good to know, thanks.

I looked into the audio codecs that Dolby and DTS have to offer.

I understand that Dolby TrueHD is an audio codec, but Dolby Atmos is not. Instead, Dolby Atmos is an object based audio format. An audio track with the Dolby TrueHD codec may or may not have Dolby Atmos in addition. Even if the Dolby TrueHD track has Dolby Atmos, the codec is still Dolby TrueHD.

I understand that DTS-HD Master Audio is an audio codec, but I'm not exactly sure what DTS:X is. For example, is DTS:X an object based audio format like Dolby Atmos? Meaning, DTS:X is not an audio codec? If so, that would mean an audio track with the DTS-HD Master Audio codec may or may not have DTS:X in addition. Also, even if the DTS-HD Master Audio track has DTS:X, the codec is still DTS-HD Master Audio. I would appreciate some clarification with this.

Makemkv and mkvtoolnix both recognize Dolby Atmos with Dolby TrueHD audio tracks. For example, it will state TrueHD Atmos as the codec for tracks that have Atmos and TrueHD as the codec for tracks without Atmos. These are both inaccurate descriptions of the codec. In both cases the codec is Dolby TrueHD. My point is makemkv and mkvtoolnix distinguish if the audio track has Atmos.

However, they don't do the same for DTS:X and DTS-HD Master Audio tracks. Why is this?

Again, I'm just trying to decide on how I want to name my audio tracks. All my 4k audio tracks (main feature) are either Dolby TrueHD or DTS-HD Master Audio. I would like to just name them by the codec in the most accurate way. Maybe I can add Dolby Atmos and DTS:X to the name also when applicable. For example,
Dolby TrueHD (Atmos)
DTS-HD Master Audio (X)

Not sure what this has to do with the topic, but yeah, Dolby Atmos and DTS:X aren't codecs, but rather metadata upon an existing stream.

Atmos will usually be carried in a TrueHD stream, but there are a disc or two which have Atmos using a lossy Dolby Digital Plus (EAC3) stream instead. It's possible to store Atmos in a PCM stream as well, but I'm not aware of any discs doing this. Atmos is properly object based, so I just substitute the channel count for "Atmos" when naming the track (eg: "Dolby TrueHD Atmos" instead of "Dolby TrueHD 7.1")

DTS:X will usually use a DTS-HD MA stream, but there are a couple discs that have DTS:X using a DTS-HD HR stream instead. I don't have any DTS:X discs, so I don't have a naming scheme yet, but I'd probably just call it "DTS-HD MA 7.1.4" since it isn't properly object based unlike its theatrical counterpart.

I'm just trying to name the audio tracks like the subtitle tracks. This is the very last step in this whole project and thought to keep it in the same thread.

Thanks for pointing out that Dolby Atmos can be used with codecs other than Dolby TrueHD. As well as DTS:X can be used with other codecs other than DTS-HD Master Audio.

I'm going to name all my audio tracks like below regardless of if they have Dolby Atmos or DTS:X.
Dolby TrueHD 7.1
DTS-HD Master Audio 7.1


Or, I can add Dolby Atmos and DTS:X to the name when applicable.
Dolby TrueHD (Atmos) 7.1
DTS-HD Master Audio (X) 7.1

I decided how to name the audio tracks. Now, I want to name the video tracks, didn't see that coming.

Do all 4k blu rays use HEVC Main10@L5.1 for the main feature? How would you name the video tracks based on the format/codec?
