Keeping in mind that if you draw a line from Texarkana to the Boot Heel of Missouri, then everything above that line is going to mean averaging 40 miles per hour drive time: your list ( and most of the advice so far) is throwing too big a loop to do in three days.
My advice is choose between:
1) Hot Springs are in Hot Springs in the south middle of the state. Plenty to do there with Hot Springs National Park, Gulpha Gorge, Mid America Science Museum, tourist stuff in Hot Springs. Hiking in the Ouachita National Forest, canoeing about 45 minutes away on the Caddo River.
2) Petit Jean and maybe Mount Magazine State Parks. Beautiful lodges, spectacular views, waterfalls, caves a first class antique car museum, rock formations, canoeing on lakes and more trails than you can hike in 3 full days.
3) Northwest Arkansas (Fayetteville, Rogers, Bentonville) More city activities but a lot of fun. Crystal Bridges Art Museum, Daisy BB Gun Museum, Native American Museum, nice shops in downtowns squares, destination for dining, hiking on Mt. Sequoia and canoeing not too far away on the Mulberry River.
4) Eureka Springs. Not as good for kids in my opinion, lots of cool shops and bars, good trout fishing nearby on Beaver Tailwater. Biggest two attractions are The Passion Play ( not open until April) and the Eureka Live Drag Queen Show, so it is kind of "different".
5) Jasper/Ponca. As pretty as anywhere in the USA. Canoeing and hiking on the Upper Buffalo, Lost Valley, Elk, wildlife and historic buildings in Boxley Valley. Arkansas Grand Canyon. Lots of unique cabins to stay
in.
6) Mountain Home, Bull Shoals, Norfork ( where I live and close to Gunny) North Central Arkansas. Some of the best trout fishing in the world in White and Norfork River, Dry Run Creek for those under 16. Canoeing on Middle Buffalo and Crooked Creek ( March is a little early but doable) Blanchard Springs Caverns and Mirror Lake. Many hiking trails, waterfalls, etc. Easy day trip to Bass Pro Headquarters, Wonders of Wildlife or Top of the Rock.
Let me know if you need more info.
