Flour to HANDS, not to the dough. I'm serious. What is happening is that the oils/moisture on your skin is sticking to the dough (whatever sort). So wash hands, dry well and then dust with flour back AND front- use at least 1 tablespoon and shake off excess to one side to use under the dough later. Then punch the dough, fold and whack it until it comes together. At least 3-5 times. Then knead or not depending on recipie. DON"T KNEAD MUFFINS, and scones only lightly. Chilling the dough once it's come together does help.
Or you can embrace the sticky, and then when the dough comes together rub off the sticky bits into the dough (only if hands are clean). Dough behaves a bit like bluetack in that it can be rubbed into balls that attract other balls.

Don't add all your moisture at once. The weather can change things a fair bit. Either flour or oil your hands.

Use lots of flour on the bench or board, rub flour into your rolling pin and rub flour onto your hands before handling dough.

Be sparing when adding more flour as you can accidentally use too much and throw off the ratio. I’m told that continuing to knead makes it go smooth elastic and become less sticky but maybe a dough scraper would help get it off the surface and back into the dough ball until it reaches that point.

I’m not a hugely experienced baker but hopefully that helps somewhat

When you're mixing in the bowl, if your dough is coming away from the bowl easy then you've got enough flour in there. Before you chuck your hands in there flour them too.
