This is going to sound obvious yet nobody ever does it and it really helps to make things so much clearer and easier to decide. Go through your current tv service and write down every channel that you absolutely must have because those channels have certain shows that you just can't live without and that are only available on that particular channel.
Every tv service, whether streaming, or cable, or satellite, has a page where they list all of their available channels. Here is the one for Youtube TV. Just put in your zip code to see the channel listing/availability for your area.

Go through their channel listing and see if they offer all of those must have channels that you wrote down. If they don't, then Youtube TV may not even be in consideration for you depending on how firm you are about those "must haves". If it does have all of them then go ahead and add up what the cost will be to get them all (maybe not all of them are available in the Youtube TV basic package and you will have to pay extra to get some of them as "add ons", so you need to add up the total cost). Now compare that total cost to what you currently pay, and if Youtube TV has all your must haves at a cost that is cheaper than what you pay now then it is a no brainer and you should give up what you currently have and change over to Youtube TV (unless of course there is another service or combination of services that offers everything you want even cheaper than that). If it doesn't have all your must haves it still might be worth switching over if it is cheaper and the cost savings are enough to justify giving up whatever "must have" channels they didn't have, but only you can made that call.
Do a google search for the channel list for all the other streaming cable tv replacements (Sling TV, FuboTV, Hulu, etc) to see what channels they have on offer so you can find the cheapest combination of services that will get you everything you have to have.
As far as tv's go, if the decision ever comes down to getting a slightly better tv or a slightly bigger tv, in most instances your money and happiness and viewing pleasure are usually going to be better off with the bigger tv as long as it is a decent tv.
Speaking of tv size, nobody in the history of tv purchases has six months down the road said "I sure wish I had gotten a smaller tv". Never. No matter how enormous a certain screen size may look at the moment, after six months of owning it it is no longer going to look that big and like every single other person you are going to be thinking "yeah its ok but bigger would be even better". Get the biggest you can justify and keep in mind that you are going to have it many years which will make the investment easier to stomach.
This is an excellent tool/site for comparing any two TV's in detail and finding out which one is actually better, and how much better in what areas, and what all of their individual strengths and weaknesses are to help you determine which tv will be the best fit and value for you. I highly suggest you use it to compare any TV's you are considering, and read their reviews on those TV models as well.

The Samsung Q60B is a decent tv but the best two tv's in that same general price range are the Hisense U8H and the TCL R655 and they both go on sale fairly regularly. Both have significantly better pictures and features. Which one of those two is very slightly better comes down to a few relatively minor personal preferences and both are excellent.
As others have mentioned I highly suggest getting the Roku service which is free to use as long as you have a Roku device or it is already built into your tv. It has by far the most free streaming content, is by far the easiest to use, and has by far the best search capabilities to find programming to watch that would be of interest to you. At any given time there are something like 500,000+ programs and movies available to watch through Roku, a sizeable portion being free.
Some TV's already have Roku built in but if not Roku can be added to any tv, just buy a Roku device for $40-100 depending on which one you want (they all give you access to the exact same programming, the differences are in what features the remotes have, whether they will stream in Dolby Vision, etc) and plug it in to an HDMI port on your tv and you now have access to all of the Roku programming. There is no monthly fee to use Roku and that would give you access to all of their free programming. Roku also offers ALL of the popular stand by's you can pay for such as Amazon Prime, Netflix, HBO, Showtime, STARZ, Hulu, MGM+, Paramount+, AMC+, Britbox, etc. There is next to nothing available anywhere else that isn't available through Roku, but Roku has lots of extra content (especially free content) that isn't available through other services.
Feel free to PM with any questions.
