If you have rum extract that will work, but lessen the amount. Just a tsp or so will do, depending on what you are baking. You can use rum extact in place of the rum. I don't have any alcohol in the house & I use extracts in their place. I use almond extract in place of amaretto also.
Here are my recommendations. Your basic ingredients are 80 proof rum, sugar and vanilla beans. At the recommended proportions, the rum and sugar are plenty effective preservatives. You can use either light or dark rum, but it should be a good call 80 proof rum and not a bargain bottom shelf rum. I most often use Ron Rico.
