For sous vide, Anova and Breville Joule are the most popular ones, but there are tons of others now. They all seem to work. Personally, I'd avoid the Joule because it can only be controlled via a phone app. Something with physical controls on the device is quicker and easier. I'd avoid bells and whistles such as Bluetooth and Wifi connectivity. They usually don't work all that well, have connectivity problems, and add close to zero value. More trouble than it's worth.
I use a Luvele vacuum sealer, which works well. Again, there are lots of others. Foodsaver, Anova, Nesco, etc. I'd look around for reviews on the web. Wirecutter did one recently. Perfection would be chamber vacuum sealer. Those things are great and suitable for liquids. But they are large, heavy, and expensive.
