Aqua is very nice! I would love to have an ecash fedimint in there too. Imho, would like to be able to hide/disable on chain. My on chain is cold, not on hot mobile wallet. Have option to receive & send any source though (on chain, liquid, lightning, ecash), but funds at rest either liquid or ecash. Small amounts like zaps and pizza go ecash, larger amounts go from liquid. Sorry, but I still want fees generally less than 0.2%. Lightning for the rails between via things like boltz's awesome service. Only for really big amounts or funding/defunding liquid should one need to break out a cold wallet to move on chain utxos.
