Used to be about all we knew was to mix 3/4 cup corn sugar & water, boil it then mix it with your wort in a bottling bucket. It was hit or miss. Now we have things like our hosts carbonation calculator https://www.northernbrewer.com/pages/priming-sugar-calculator It takes some of the guess work out of it.
Then came the tabs, drops or whatever they call the compacted sugar you drop right in the bottle. Still hit or miss.
I keg almost everything and prime the kegs most of the time. When you get your keg setup you will find it gives you the ability to carb without refrigeration and taking up valuable fridge space. Consider buying or building a spunding valve. Just Google it and there is info on both. You can connect it while the sugar is working and it will release pressure above your setting. I just wing it on the sugar using table sugar, give it enough time, like two weeks and connect the spunding valve. If it's too carbed it will release pressure. If under carbed either wait more or hook up your CO2 to finish it.
Good luck. Carbonation is one of those things you will get better at once you get used to your equipment.
