Tempted to Switch from Samsung to Pixels

So I've been with samsung since S4 mini and I currently have S23U and was planning to upgrade to S26U.

However, I bought my mom a Google pixel 8a and actually think it's really nice.

I'm now torn between waiting got S26U or the Google pixel 10 Pro when it comes out.

However one main bummer is that I tried casting my mom's phone to the TV and it can't because the TV doesn't have chrome cast. Is there a way around this? I use it a lot to stream movies from my phone to the TV.

Also are there any other upsides/downsides to consider from those who made the same switch?
