My vote for good diesel is to start with the basic ULSD (Ultra-Low-Sulfur-Diesel) fuel from my local gas station. I like to use a name brand and a newish station. All I'm looking for is basic clean consistant ULSD fuel. If I can find that, the next step is to put in some additives to add some lubricity, protect it from bacteria, and slow down the gelling in cold weather.
Lots of companies sell a basic diesel additive. John Deere and Opti-lube are two brands I use ..... mostly because I am familiar with them - having used them in the past. Of the two, I'd lean toward JD just because they have the most to gain by selling a decent product.
And if you don't want to do any of this, keep in mind that dirty diesel fuel problems are only a hassle, not a disaster. In 60 years now of working with tractors I've never personally seen a diesel that was permanently damaged by diesel fuel or additives of any kind.... maybe with the exception of starting fluid i.e. ether.

But no additives for lubricity on these older diesels can lead to failure, of your injection pump.
