Is it reasonable to use br?

Question

css

When laying out such a structure, which of the options will be more correct and beautiful?
1. Use br to transfer - I read / heard somewhere that it is not recommended to use it at all and you can safely do without it.
2. Wrap each input + label row in a block element and the problem will sort of disappear by itself .. but a lot of different wrappers will multiply, not at all ok.
3. Use fixed widths - an extreme option, with fixed widths there may be problems with adaptability, etc., IMHO.

ps: sorry for the possibly holivar/stupid question, but I want to learn how to do everything according to feng shui and not worry about it :)

Answer 1

<label class="checkbox checkbox--block">
    <input type="checkbox" />
    Some label
</label>

Answer 2

but a bunch of different wrappers will breed, not at all ok.

where are the bunch of wrappers from? The title, list and each input are wrapped in a label. Or dl-dt-dd and also input to the label.
