The best measure of central tendency for these data is the median, as it is not affected by extreme values (like the "5 or more" response in this case). The mode could also be considered a valid option, but in this case, there is no clear mode as there are no repeated values. The mean and weighted mean are not appropriate because the data is not numerical, it is categorical.
