I think it is because if the tap handle doesn’t overhang the sink then wet hands drip water over the bench behind the sink. I have an undermount sink with same issue due to required setback from sink and we are learning to shake hands before turning off tap. Pro for wall mount no gunk around base of tap Negative according to my husband who refused to have wall mounted is the tap connections are in wall so if you get any leaks it’s hard to fix. But this goes same for shower I guess. We did have a faulty basin tap that leaked inside the handle area and down into cabinet so had to get replaced so I didn’t-push for wall mounted again.

Just looking at them on their own (not in the context of the bath/basin) I really like the one with the black on it - 2nd... but I think you're right to try and match the bath and basin taps. That bath and matching basin are absolutely divine! Amazing shapes! And judging by the pic and your other queries, you also have a fabulous sense of styling and shouldn't need anyone else's opinions...? (imho)

Flick-mixers are the bees-knees of taps, everywhere! Other than to match a period decor, I don't understand, why anyone would want conventional taps anymore. Here's why: There is only *ONE* piece of tapware to clean per basin; they are quick and convenient to use, especially if you have frail hands, soapy hands, small hands, anything; you can set them to a certain position and then 'off' and 'on' them without having to re-locate your preferred temperature again; the flicker handle is positioned over the actual sink/basin, so wet hands drip into said basin and not on your counter-top. they come in plenty of stylish designs.

We have a zip built into our ceasar stone bench top next to our sink. We opted for the font (the mesh waste) and riser (it attaches to the bottom of the zip to give it extra height) We have instant boiling water (you can only use it when you press the safety switch located under the boiling water switch) chilled filted water and sparkling water. The sparkling water is sensational. We worked out the ratio and it is of equal value (replacing the canister as to buying X amount of bottles of mineral water over the same period) and we drink a lot of it (we are a family of 5) The unit itself sits under the sink and is smaller than a case of beer, and next to it is a C02 canister (resembling a small tube) We now don't have any empty water bottles in our fridge or cupboards, we no longer have a shelf full of mineral water (the filter water is so pure and clean) and I don't have a kettle on display day and night!! Yes the initial outlay is expensive but it looks fantastic is easy to use and I would highly recommend it.
