There's a reason that people in The Netherlands, Germany, Finland, Sweden, Italy, China, France and dozens of other countries all ride upright Dutch bikes for everything but racing. Apes were designed for leaning forward, us humans not so much. Leaning forward works great if you're putting out enough power that none of your weight is resting on your hands, wrists, arms, and shoulders. Otherwise leaning forward is more detriment than benefit.

Even pro cyclists ride upright bikes for transportation and other non racing/training bits.

If your purpose is training & racing then a drop bar road bike is probably the right choice. Given time and experience you'll get use to the handling and it won't seem so twitchy. If your purpose is transportation or general recreational rides then an proper upright is likely a better option.
