Welcome to the forum!
What zone are you growing in? And what plants are you looking to grow If you are down south, container gardening may be your best choice for some plants, due to nematodes, and other pests that don't get killed in the winter. Up north, some things can be speeded up a little because the container will warm up sooner than the ground, especially when there is a deep freeze in the winter. Also, if your soil is not very good, it will take a while to build it up, while you can have a good soil mix immediately in containers, while working on the garden soil.
I grow a lot of things in the types of containers known as sub-irrigated planters, or SIPs. The best known brand of these is Earthbox, though some places like Lowe's and HD have gotten their brands of them in recent years. There are many threads about these, and other container gqrdening here on the forum:

Watering is a major concern when container gardening. If you have a lot of containers you are going to have to set up some sort of irrigation system; otherwise, you will be spending much of your free time watering! Unless it is one of those SIPs, a large plant like a tomato or an eggplant can dry out a 6 or 7 gal pot in a day or two. And, when pots dry out, they get lighter, so wind can blow them over. This doesn't happen with those SIPs, but even those need filled frequently - I have a drip system set up on timers, to come on twice a day, to refill them. Even once a day doesn't keep them filled, with large tomatoes and eggplants, in the heat of the summer!
