I adore both Interia and Lo and Co Interiors for hardware. They aren't cheap but I wouldn't say they are super expensive. If you use some of their statement hardware, you could just do them on lower cabinetry and leave the upper cabinetry as push-to-touch and keep it simple and a bit cheaper.

print out some large copies of your photos and draw in the handles and knobs in various combinations to compare the look...vertical handles on the doors and horizontal on the drawers or knobs on everything or knobs on the doors and horizontal handles on the drawers or..??...as you already understand there are so many variations so try the pictures and post a few variations for a poll?

In the interest of keeping your kitchen friendly to as many users as possible, may I suggest you avoid knobs of any description. Older people and those with disabilities/reduced function of the hand/arm/shoulder often struggle to grasp and pull on a knob. 'Push' closers and D (or U) shaped handles with a min of 50mm height from surface are much friendlier in this regard. We are building our retirement home and - although we are both well and dextrous at present - it is so easy (and much cheaper) to think ahead, we're discovering. Setting up the place to be comfortable for as many users as possible is also pretty satisfying. Personally I'd like brush satin steel long D handles with an elegant line. Black on black might be hard to see for some and in low light.

Your kitchen, do what you love. The style police won't be raiding and deducting points. But before you do make a decision make sure you check out the beautiful range of knobs and handles at Hepburn Hardware. https://hepburnhardware.com/ They are pricier than Bunnings, but you get what you pay for when it comes to cabinetwork hardware.
