Many of us sow in flats for material and space saving - sowing in individual pots may not be efficient unless you need only a small number of plants.

Seedlings from seeds sown close in a flat can grow together and become overcrowded, tall and spindly, difficult to separate if left too long. It's beneficial to the seedling to 'pot up' or transplant to individual containers at this point ...they benefit from transplanting in that way, but often disturbing the roots will set the growth back or stall it temporarily, they don't actually benefit or improve from having their roots disturbed - not like punching down rising dough :)

If you started your seed in individual pots (or thin using scissors as you describe to a strongest seedling), you will not have to transplant if your pots are large enough to accommodate developing roots until time to plant out in the garden.

It may be a little harder to keep the moisture content appropriate in a large container for seedling roots so you'll need to pay special attention there if you choose to go that route. Watering not frequently enough can cause the top to dry out (where the roots will first be) and watering too often can leave the lower pot zone too wet.

I agree with the above post.

You do not have to be transplanted in ideal settings.

Good luck and let us know how they are doing ! : )
