$begingroup$ @Shocked The loop is a real thing: Current enters your cap through one lead, then goes through it along its internal electrodes and through the dielectric, and finally out the other lead (usually close by the first lead). So there is a loop area spanned by these "waypoints". The smaller this loop (the smaller the capacitor typically), the smaller the ESL.

In contrast to power cables, busbars also make it possible to achieve power distribution with high power density, by mounting active components for power conversion, such as IGBT semiconductors, and passive circuit elements, such as capacitors and EMI filters for noise reduction, on the busbars.

A 1uF capacitor and a 10uF capacitor are other common ones seen in circuits. They do a good job of helping smooth out ripple noise in DC voltages. For super capacitors, a 1 Farad capacitor or even a 2 Farad capacitor is seen often on boards that need a little current even if the power goes out or the battery dies.
