O2F2 has shorter bond length due to presence of lone pair repulsion between O &F

H202 Explanation- We know that fluorine is a strongly electronegative element. So, it has tendency to attract electron density towards itself. Thus, in O2F2 , fluorine attracts electron densities towards itself resulting in smaller O-O bond. In H2O2, oxygen is not as strong an electronegative element as fluorine is. So, even though it does attract electron density towards itself but not to the extent and intensity of fluorine. So, H-H bond is not as affected as O-O bond in O2F2

H2O2 has more bond length than O2F2 Explanation- https://chemistry.stackexchange.com/questions/65079/relative-o-o-bond-lengths-in-o2x2-molecules-x-h-f-cl In Lewis resonance depictions, this can be explained by the following mesomeric structures: F−O−O−F ⟷ F−O+=O F− H−O−O−H ⟷ H−O-O- H+ The bonding within dioxygen difluoride has been the subject of considerable speculation over the years, particularly because of the very short O–O distance and the long O–F distances. Bridgeman has proposed a scheme which essentially has an O–O triple bond and an O–F single bond that is destabilised and lengthened by repulsion between the lone pairs on the fluorine atoms and the π-orbitals of the O–O bond.
