What Does Canadian Citizenship By Descent Entail For US Citizens?

I am an American no plans to move to Canada at present. If I go ahead and get proof of Canadian citizenship :

Can I hold both a US and Canadian passport? Travel on whichever one I prefer? (Even if I'm still living in the US?)

Will I have an obligation to file taxes in Canada? Can I vote in elections?

If I travel in Canada, will holding Canadian citizenship obligate me to have a Canadian drivers license, or other state-issued ID?

Does holding Canadian citizenship have implications for my US citizenship? Is there anything new I'd have to do here in my country of residence as a dual citizen?

If at some point in the future I do decide to move to Canada, would I be able to sponsor my spouse in immigrating?

I'm just spitballing here... trying to understand what my rights and responsibilities as a Canadian citizen would be, and the impact it would have on me here at home.
