Moulding planes often are made with a steep pitch to the blade,(55°-60°) which helps prevent tearout. Making profiles with or across the grain usually isn’t too much of a problem . Hollows and rounds also come in skewed versions, which makes working end grain a bit easier. The trade off is they track a little less easily.

There are a couple of traditional ways to make the profile consistent . One is to first cut a shallow rebate and start your rounded edge profile at that point so the start of the rounded profile is more defined. A filletster plane will do this. A skew version will do the cross grain more easily.
It doesn’t have to be a lot deeper than a deep scribe mark. Most thumbnail edge treatments start this way. And can be rounded with hollow planes, a dedicated moulding plane or just a hand plane to remove most of the profile followed by scratch stock .

A second it to make the profiled portion an breadboard end “ plant” on the edge. It would be easier to make, the profile and would be long grain , but would need some sort of joinery to apply to the table edge., again, with a slight offset. maybe a T&G joint and some dowels. Keep in mid the edge of a dining table takes some abuse.
