Lavenders like well drained alkaline soils so I wouldn't advise those if your soil is acid. You could try salvias if you want the blue flowers but you won't get the perfume.
Other evergreens to think about are viburnums such as Eve Price which flower in late winter/early spring tho all mine died in a very cold -25C for weeks winter. Then choisyas (mexican orange blossom), eleagnus and mahonia which will provide different foliage colours and forms and perfumed yellow flowers if you go for mahonia Charity.
Pyracantha will provide spring blossom, autumn berries and evergreen foliage and, when mature, shelter for birds. You could use topiarised forms of box or yew if you want formality.
As far as I know, Arts and Crafts is all about geometry in garden paths and structures, softened by planting so I'm not sure your lovely curvy path fits the style. Try having a good google for info or visit the local library to get design ideas.
Whatever you do, get the soil right before you plant. Work in plenty of well-rotted garden compost/manure/soil conditioner first as this will provide the conditions for nutrients and beneficial micro-organisms which will benefit your plants.
