The easiest would be the one in your home country / country of residence. Get an e-visa from there and save yourself the hassle. Can be done fully remotely (from everywhere in the world).
Actually, there is three: 1927, 1949 and 1968 - all with varying participating / ratifying countries. And in most countries only applicable for a certain amount of time per stay. Google for details.

Wise offers you both ways. You can send money directly to your Thai bank account (e.g. from a credit card). But you can also „top up“ wise in USD or EUR first, then convert it into THB and then send THB to Bangkok bank. The first way is a bit more convenient. The latter way is a bit cheaper (and you could make use of automatically converting when the exchange rate is good / meets a chosen threshold). I usually do the latter.

I would assume that was NOT a visa run. A visa run is traveling to a nearby country to obtain a new visa to return. It was rather a border run / or border bounce. And it would seem to particularly not have involved any visa, but having happened on visa EXEMPT. And thus, visa exemptions are limited to two entries per calendar year (on land borders).
