If after you slide the saddle(seat) forward on the rails, and loosen and twist the “rise” handlebars in towards you about 45 degrees and you still don’t get the position you want, I’d start with different bars. Reason being is that you want both closer AND higher.

If it does work for you then just adjust the combo brake lever shifters for the new position by loosening and rotating them so the levers are comfortable.

The way stems work is with an angle and length, if you go shorter, then even the steepest angle won’t give you much rise. They do have adjustable ones that can give you a ton of rise, then in combo with turning you bars towards you, it may do the trick (plus you can inch it back down as you become more flexible and fit). https://www.amazon.com/Wake-Adjustable-Mountain-Handlebar-Lightweight/dp/B07BQ17PMX/ref=pd_lpo_sbs_468_t_1/144-2945294-1081954?_encoding=UTF8&refRID=A2YG64KKK78YN2KPYHN4

The option I would go with is some cheap downhill mtb bars with the appropriate amount of rise, and turn them in. If I found that it wasn’t enough then I would get a shorter stem and in conjunction with these bars I would be guaranteed to be pretty dialed in. It’s a matter of preference which one you would try first, but I know which way I would. These ones are out of stock but I’ll share them as an example. https://www.jensonusa.com/Spank-Spoon-60-Handlebar

Think these ones are a little less rise but in stock https://www.jensonusa.com/Answer-Alumilite-Riser-Bar

You also could go full cruiser bars, they will have a more swept back feel and aesthetic, but regardless of bar or stem choice double check before you order that it will fit what you have. If you put together an order, people here will do a final look over it to make sure it will fit if you need the help.
