Is there a native container block?

I find the row and column blocks irritating to work with – setting margins and padding is NOT intuitive – if I can do it at all. I don’t like the dash things that are evidently some kind of preset paddings or margins – why are they the default? Why are they there at all? Why can I only (after having to drill down) set margins to the top and bottom but not sides? And I never see the option to set full widths which is apparently some sort of ongoing thing (https://github.com/WordPress/gutenberg/issues/41579).

When I use non-native blocks in templates they show up as unsupported when I try to copy the theme or make a child theme. But I use them because they offer more settings and less irritation. (I like the GreenShift Row block and container block & Getwid Section block among others.)

Why isn’t there a native container/section block that a row or columns can be placed within?
