Should a budget surplus fund tax cuts, cost-of-living support, and public services?

No

Yes and no, they should support these things somewhat but also these supluses need to be used on long term country improvements.

Supports for cost of living should only be be given to people who work, who have disability’s and require care, those who are careers and those who are single parents.

These are 2 different things and should not be lumped together. Public services should be funded by budget surplus.

to a degree. it should also fund defense, national autonomy, housing, sovereignty, large emergency funds and self-sufficiency.

I think tax should be better spent but cost of living supports and public services should be better invested in.

Should have a choice to accept the tax cut or instead select where you want the equivalent funds to go

Should be used to provide more multi unit houses that only first time buyers can purchase, should be used for medium transport infrastructure

It should fund infrastructural development as well. Otherwise it's a plaster being put on a gaping wound.

I think the surplus should be divided between investment in public services and bracing for economic downturn

Should be invested in education and healthcare reform Tax reform not cuts or hand-outs as these act as a bandaid

I don't think tax cuts are required currently, but cost-of-living support and public services should be funded by a surplus.

Again, it depends on the country's circumstances at that time. If overall debt is low, there is a rainy day fund in place with enough backup finance in it, then possibly look at cost of living support, healthcare support etc.
