Ngths definitely sounds nice when interpreted literally in the ipa /ngths/

There are other weird things in English. Like ghost letters influencing pronounced letters like Cake being/Kākᵉ/

Yeah

Also with things like ough, which is pronounced many different ways depending on external factors

Yeah. Also, there are languages that also have consonant clusters like English. Dutch has Slechtstschrijvend. Polish has Szczebrzeszyn. Georgian has Gprtskvni. All languages have a few weird words. It just that English has an absurd amount of them.
