Text box manipulation and find and replace

I have a couple Figma mysteries I am trying to solve:

1-I am looking for quick ways to achieve more accurate padding measurements in my handoff files. I need to get my text boxes to hug the text to do so accurately. It looks like Growth Vertical is not active any more-how can I quickly set all my text boxes to match the text height?

2-Is there a feature that allows us to select one color or text, line wieght and replace it everywhere? This has been a feature in Adobe for so long,and the Figma plugins I have found are cumbersome and time consuming.

Thank you!
