This article in The Conversation (which is a new publication to me) goes through some of the alternatives and potential augmentations for GDP.

One approach is to have a dashboard of indicators that are assessed on a regular basis. For instance, workers’ earnings, the share of the population with health insurance and life expectancy could be monitored closely, in addition to GDP…

Another approach is to use a composite index that combines data on a variety of aspects of progress into a single summary number. This single number could unfold into a detailed picture of the situation of a country if one zooms into each indicator, by demographic group or region.

One challenge is to select the dimensions that should be covered. Through an international consultative process, the commission led by Sen, Stiglitz and Fitoussi defined eight dimensions of individual well-being and social progress, including health; education; political voice and governance; social connections and relationships; and the environment.

They also mention the Better Life Index from the OECD and the Human Development Index from the UN.
