My overall advice is unless you're a designer flexing your skills is to focus less on the design and more on the actual writing! The internet is littered with the emaciated husks of nice good looking sites hosting nary an entry beyond "How I Made My New Blog With X"
Let's start with the two you mentioned: looking at the source code, one's actually built from a squarespace theme, and the other is likewise built from a wordpress theme, feels like an slightly older one given it's not mobile responsive. That's not a knock, by the way - sometimes you want an audience that don't use phones or deliberately flock to the retro vibe.
I don't know your budget or capability to self-code, but browsing squarespace's themes would be what I would recommend if you have a higher budget, and likewise doing the same with wordpress if you're operating on a shoestring mindset. There's some gorgeous ones on both, though squarespace is far more curated and caters to a more modern/slick looking audience and clientele.
