JP,
The graphic below is what I get. Also using Sonoma here. What I get is perhaps a little unexpected. Copying one cell, the pasted result is a Table Cell with the same content, in a One-Cell table with the same table name as the Four-Cell table in Numbers. If enough users provide feedback to Apple that they don't like that behavior, they will take a look at it.
I'm not sure it would be considered a flaw, even if it's different than before. Could be a "feature".
The sure way to get only text on the Clipboard is to click down to the text level of the Numbers cell and Select the text content before copying.
Then when Pasting into Pages, you can CMD-V and your text will go into a Text Box. A bit unusual, but again interesting as a feature. Shift-CMD-V or Shift-OPT-CMD-V will give you plain text in the body of the Pages document.
Hope that helps.
Aloha from frigid but Sunny Pittsburgh.
Jerry
