What is the better option for trying to set up my 5 year old daughter financially?

I was originally thinking about going with a 529 plan but now I'm contemplating going with a UGMA/UTMA plan.

My main worry with the 529 plan is the case that my daughter doesn't attend college. There are no other sibling or cousins to fund their education. I know of transferring 35K to Roth IRA for her, but what are the tax implications for that vs the UGMA/UTMA plan.

I also understand that in Louisiana, at age 22, the money is in her control for the UGMA/UTMA route. She is only 5, so it's not yet determined if she will be an impulse buy now person and waste it.

I will be set up fairly nicely for retirement in about 15 years, but I also was diagnosed with Stage 4 kidney cancer 5 years ago. I have seemed to beat the cancer, but no one knows if I get a reoccurrence and my timeline for saving for retirement is cut short. If that occurs, she will be set with the amount of money she will inherit (I'm now divorced), so this advice recommendation is for me making to the retirement age and having enough to live comfortably but also providing a good start to my daughter's future.

Any experienced financial guys out there that can help shed some information would be much appreciated.
