Is ROTH IRA the best vehicle for leveraged ETF?

I am relatively new to investments and I am managing ROTH IRA and taxable account at the moment.

From my understanding, ROTH IRA funds are tax free at realized gains. so I wonder if ROTH IRA is the best 'vehicle' for short term investment. I understand there is also no tax loss harvesting either.

I just have not heard people doing leveraged ETFs under ROTH IRA so I wanted to check if I am missing anything, before I consider.

Thanks!
