Thanks, it is absolutely useful.

After consideration, a semicolon would be too strong; a hyphen would be

Same here, I find a semicolon would be too strong.

Disagree on this one: the last part should still be in the sentence that
starts with “Note that”. There is no problem in having multiple
semicolons to separate parts on the same level.
